A new wireless sensor was designed, fabricated, and applied for in situ monitoring of tensile force at a wound site. The sensor was comprised of a thin strip of magnetoelastic material with its two ends connected to suture threads for securing the sensor across a wound repair site. Since the sensor was remotely interrogated by applying an ac magnetic field and capturing the resulting magnetic field, it did not require direct wire connections to an external device or internal battery for long-term use. Due to its magnetoelastic property, the application of a tensile force changed the magnetic permeability of the sensor, altering the amplitude of the measured magnetic field. This study presents two sensor designs: one for high and one for low-force ranges. A sensor was fabricated by directly adhering the magnetoelastic strip to the suture. This sensor showed good sensitivity at low force, but its response saturated at about 1.5 N. To monitor high tensile force, the magnetoelastic strip was attached to a metal strip for load sharing. The suture thread was attached to the both ends of the metal strip so only a fraction of the applied force was directed to the sensor, allowing it to exhibit good sensitivity even at 44.5 N. The sensor was applied to two ex vivo models: a sutured section of porcine skin and a whitetail deer Achilles tendon. The results demonstrate the potential for in vivo force monitoring at a wound repair site. [ABSTRACT FROM PUBLISHER]

We report theoretically and experimentally a passive bidirectional current–voltage ( $I$ – $V$ ) converter, capable of converting input currents into output voltages, and conversely, input voltages into output currents, based on a multiphase heterostructured magnetoelectric (ME) ring. The ME ring has a coil-wound, intermagnetically biased magnetostrictive–piezoelectric (MS–PE) heterostructure, in which an axially polarized PZT PE ceramic ring is bonded between two circumferentially magnetized, intermagnetically biased Terfenol-D short-fiber/NdFeB magnet/epoxy three-phase MS composite rings. In $I$ – $V$ conversion, a current applied to the coil induces a vortex magnetic field to the ME ring, resulting in an open-circuit voltage from the ME ring because of the direct ME effect. In voltage–current ( $V$ – $I$ ) conversion, a voltage applied to the ME ring produces a circumferential magnetic induction due to the converse ME effect, leading to a short-circuit current from the coil. The converter exhibits simultaneously large $I$ – $V$ and $V$ – $I$ conversion factors of $\sim 0.3$ V/A and $\sim 0.2$ mA/V in a broad non-resonance frequency range up to 80 kHz as well as enhanced conversion factors of $\sim 7$ and $\sim 25$ times at the resonance frequency of 122 kHz, respectively.

When brothers Jamie and Glen Selby, aged 5 and 7, arrived at the Shriners Burns Institute in Denver, Colorado, in July 1983, more than 97% of their skin had been destroyed by a fire they had accidentally started while playing in an abandoned house. The boys were so badly burned that their outlook was grim-a 6-year-old friend who was also in the fire died from his injuries?but Jamie and Glen were lucky. Not only did they survive, but they were also some of the first patients to benefit from a new burn treatment nicknamed test-tube skin. [ABSTRACT FROM PUBLISHER]

Clinical data from human chronic wounds implicates biofilm formation with the onset of wound chronicity. Despite the development of novel antimicrobial agents, the cost and complexity of treating chronic wound infections associated with biofilms remain a serious challenge, which necessitates the development of new and alternative approaches for effective anti-biofilm treatment. Recent advancement in nanotechnology for developing a new class of nanoparticles that exhibit unique chemical and physical properties holds promise for the treatment of biofilm infections. Over the last decade, nanoparticle-based approaches against wound biofilm infection have been directed toward developing nanoparticles with intrinsic antimicrobial properties, utilizing nanoparticles for controlled antimicrobials delivery, and applying nanoparticles for antibacterial hyperthermia therapy. In addition, a strategy to functionalize nanoparticles towards enhanced penetration through the biofilm matrix has been receiving considerable interest recently by means of achieving an efficient targeting to the bacterial cells within biofilm matrix. This review summarizes and highlights the recent development of these nanoparticle-based approaches as potential therapeutics for controlling wound biofilm infection, along with current challenges that need to be overcome for their successful clinical translation.

Current methods in treating chronic wounds have had limited success in large part due to the open loop nature of the treatment. We have created a localized 3D-printed smart wound dressing platform that will allow for real-time data acquisition of oxygen concentration, which is an important indicator of wound healing. This will serve as the first leg of a feedback loop for a fully optimized treatment mechanism tailored to the individual patient. A flexible oxygen sensor was designed and fabricated with high sensitivity and linear current output. With a series of off-the-shelf electronic components including a programmable-gain analog front-end, a microcontroller and wireless radio, an integrated electronic system with data readout and wireless transmission capabilities was assembled in a compact package. Using an elastomeric material, a bandage with exceptional flexibility and tensile strength was 3D-printed. The bandage contains cavities for both the oxygen sensor and the electronic systems, with contacts interfacing the two systems. Our integrated, flexible platform is the first step toward providing a self-operating, highly optimized remote therapy for chronic wounds. [ABSTRACT FROM PUBLISHER]

Diabetic foot ulcers represent a significant health issue. Currently, clinicians and nurses mainly base their wound assessment on visual examination of wound size and healing status, while the patients themselves seldom have an opportunity to play an active role. Hence, a more quantitative and cost-effective examination method that enables the patients and their caregivers to take a more active role in daily wound care potentially can accelerate wound healing, save travel cost and reduce healthcare expenses. Considering the prevalence of smartphones with a high-resolution digital camera, assessing wounds by analyzing images of chronic foot ulcers is an attractive option. In this paper, we propose a novel wound image analysis system implemented solely on the Android smartphone. The wound image is captured by the camera on the smartphone with the assistance of an image capture box. After that, the smartphone performs wound segmentation by applying the accelerated mean-shift algorithm. Specifically, the outline of the foot is determined based on skin color, and the wound boundary is found using a simple connected region detection method. Within the wound boundary, the healing status is next assessed based on red–yellow–black color evaluation model. Moreover, the healing status is quantitatively assessed, based on trend analysis of time records for a given patient. Experimental results on wound images collected in UMASS—Memorial Health Center Wound Clinic (Worcester, MA) following an Institutional Review Board approved protocol show that our system can be efficiently used to analyze the wound healing status with promising accuracy.

This paper investigates the optimal arrangement of the coils in a wound-type interphase reactor to avoid the decreased inductance due to local saturation in the core when operated with high dc current. In theory, the direct currents and the related magnetomotive forces in the two ways of an interphase reactor are equal, and this compensation leads one to conclude that the global flux in the yokes is zero. However, the dc currents in the coils produce a significant leakage flux that flows locally in the core. If the coils are not suitably arranged and if the dc current is high, the leakage flux causes local saturation, a drop in the inductance, and noticeable circulation of a triple harmonic current through the reactor. Such a phenomenon is investigated by means of both a simplified field model and three-dimensional magnetostatic simulations. A number of criteria for the arrangement of the coils to improve operation are derived and applied to a real rectification system used in an electrolysis plant. Some in situ operational measurements of both the original and the improved interphase reactor are reported. [ABSTRACT FROM PUBLISHER]

Lymphatic vessels are a part of the circulatory system in vertebrates that maintain tissue fluid homeostasis and drain excess fluid and large cells that cannot easily find their way back into venous system. Due to the lack of noninvasive monitoring tools, lymphatic vessels are known as forgotten circulation. However, the lymphatic system plays an important role in diseases such as cancer and inflammatory conditions. In this paper, we start to briefly review the current existing methods for imaging lymphatic vessels, mostly involving dye/targeting cell injection. We then show the capability of optical coherence tomography (OCT) for label-free noninvasive in vivo imaging of lymph vessels and nodes. One of the advantages of using OCT over other imaging modalities is its ability to assess label-free blood flow perfusion that can be simultaneously observed along with lymphatic vessels for imaging the microcirculatory system within tissue beds. Imaging the microcirculatory system including blood and lymphatic vessels can be utilized for imaging and better understanding pathologic mechanisms and the treatment technique development in some critical diseases such as inflammation, malignant cancer angiogenesis, and metastasis.

We evaluated a nonthermal plasma jet for a respective use to prevent infections from bacteria and yeasts. The plasma jet is generated from the flow of ambient air with 8 slm through a microhollow cathode discharge assembly that is operated with a direct current of 30 mA. With these parameters, the temperature in the jet reaches 43 ^\circ\C at 10 mm from the discharge. Agar plates that were inoculated with Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter baumannii, and Candida kefyr were treated at this distance, moving the plates through the jet in a meander that covered a 2 cm by 2 cm area. Different exposure times were realized by changing the speed of the movement and adjusting the distance between consecutive passes. S. aureus was most responsive to the exposure with a reduction in the number of colony forming units of 5.5 log steps in 40 s. All other microorganisms show a more gradual inactivation with exposure times. For all bacteria, a clearing of the treated area is achieved in about 2.5–3.5 min, corresponding to log-reduction factors of 5.5–6.5. Complete inactivation of the yeast requires about 7 min. Both S. aureus and C. kefyr show considerable inactivation also outside the immediate treatment area, while P. aeruginosa and A. baumannii do not. We conclude that differences in the morphologies of the membrane structures are responsible for the diverging results, together with a targeted response to different agents provided with the plasma jet. For the gram negative bacteria, we hold short-lived agents, acting across a short range, responsible, while for the other microorganisms, longer lived species seem more important. Our measurements show that neither heat, ultraviolet radiation, nor the generation of ozone can be responsible for the observed results. The most prominent long lived reaction product found is nitric oxide, which, by itself or through induced chemical reactions, might affect cell viability. [ABSTRACT FROM PUBLISHER]

In this brief two sliding mode control alternatives to regulate the stator voltage amplitude for a stand alone wound rotor synchronous generator are presented. Both controllers use the stator voltage d-component error in the sliding surface. In a first case an outer proportional-integral (PI) loop controller is added to provide the proper d-voltage component reference. The second approach consists in extending the dynamic system to include the integral term as state variable and to modify the former sliding surface by adding this new state. Finally, both simulations and experimental results validates the proposed algorithms. [ABSTRACT FROM PUBLISHER]

The design and the electric and emission characteristics of a handheld air plasma spray are presented. The plasma is generated by 60-Hz periodic discharges between two concentrically cylindrical electrodes. A ring magnet is used to rotate arc discharges, which sprays outward by an airflow. The rotation of arc discharges keeps the generated plasma in nonequilibrium state and at relatively low temperature (\sim \!\!55\ ^\circ\C). The plasma effluent still contains high-energy electrons which dissociate molecular oxygen into atomic oxygen. The emission spectroscopy of the plasma plume reveals that the plasma effluent, which carries abundant atomic oxygen, extends from the cap of the plasma spray about 25 mm. Using pigs as the animal model, in vivo tests of stopping wound bleeding and postoperative observation of wound healing by this air plasma spray were performed. The results show that the bleeding from a cut to an ear artery is stopped swiftly; this air plasma spray also shortens wound healing time to about half (from 14 days to 8 days) after stopping the bleeding of a cross-cut wound in the ham area.

This paper proposes a three-phase five legged wound transformer core constructed of two high permeability Si-Fe wound cores and two conventional Si-Fe wound cores. The two large internal wound cores are manufactured of high permeability, grain-oriented electrical steel. The two small outer wound cores are manufactured of conventional, grain-oriented electrical steel. The specific arrangement is based on experimental evidence concerning the peak flux density non-uniformity of the typical three-phase five legged wound transformer core, constructed of the high magnetization grain-oriented steel. Since the peak flux density of the two outer cores is lower than the two internal cores, low cost, low permeability, conventional grain-oriented electrical steel can be used for the outer cores. Losses, excitation currents, flux waveforms, and their harmonics contents are presented in this paper. A comparison of the mixed three-phase transformer core and the typical one is also carried out.

In recent years, researchers have proposed transformerless solutions for connecting renewable-energy power plants to the grid. Apart from lack of efficiency and increased cost and weight of the transformer, one of the reasons is the dc input current that causes transformer saturation. The purpose of this paper is the development of a finite-element computational tool that is going to aid transformer manufacturers in designing distribution transformers specifically for the renewable-energy market. It is based on a generalized macroscopic representation of electrical steels used in the transformer manufacturing industry that enables the accurate evaluation of electromagnetic field distribution of transformer cores under heavily saturated conditions. Its advantages over conventional formulations include numerical stability, numerical accuracy, and reduction of iterations of the Newton–Raphson method. An experimental verification of the proposed method is carried out. [ABSTRACT FROM PUBLISHER]

This paper presents the measured experimental results from a four-pole toroidally wound induction machine, where the stator is constructed as a prewound foldable strip. It shows that if the machine is axially restricted in length, the toroidally wound induction machine can have substantially shorter stator end windings than conventionally wound induction machines, and hence, it shows that a toroidally wound induction machine can have lower losses and a higher efficiency. This paper also presents the employed construction method, which emphasizes manufacturability, and highlights the advantages and disadvantages of this method. [ABSTRACT FROM PUBLISHER]

This paper presents a sliding mode control for a wound rotor synchronous machine acting as an isolated generator. The standard dq model of the machine is connected to a resistive load. A switching function is defined in order to fulfill control objectives, and the ideal sliding dynamics is proved to be stable. From the desired surface, the standard sliding methodology is applied to obtain a robust and very simple controller. Numerical simulations and experimental results validate the control law and show good performance and a fast response to load and reference changes. [ABSTRACT FROM AUTHOR]

A floating magnetic rotor is synchronized to a rotating magnetic field in the developed pump. We cannot measure or calculate the magnetic torque using a general measurement method because the angle theta (\theta) represents the unknown factor between the magnetic field and the magnetic moment on the magnetic rotor. We have converted the relationship between the rotating magnetic field and the rotation of the magnetic rotor to an electrical signal using Faraday's law. Converted signals have a phase difference that is converted to the angle theta (\theta) in the magnetic torque. This has allowed us to calculate the magnetic torque. [ABSTRACT FROM AUTHOR]

The MgB2 coil wound with a parallel conductor composed of two MgB2 tapes with insulation has been developed. The tape is obtained by the rolling process from the round wire which is fabricated by in-situ method. The performances of tapes, such as critical current density and ac losses, are higher than that of round wires in case that the transverse magnetic fields are applied to the tape in direction of the parallel to the flat face of the tape. We proposed as a candidate of applying the tape to a conductor with large current capacity that the parallel conductor is composed of insulated tapes. We fabricated a tape with aspect ratio of two from a round wire with diameter of 0.8 mm as a strand for the conductor. The coil is composed of two coils that are jointed each other in series. At the joint, two strands are transposed to be identical the inductances of two strands. The inner and outer diameters of the coil are 65 mm and 107 mm, respectively. The length of the coil is 53 mm. The total turn number is 540 turn. The magnetic flux density at the center in the coil is 1.31 T when the transport current is 200 A. In this paper, the design and the test results of the MgB2 coil wound with the conductor are shown and the critical current properties and ac loss properties of the coil are discussed [ABSTRACT FROM AUTHOR]

Existing conjugated-polymer actuators typically take the form of benders or linear extenders. In this paper, a conjugated-polymer-based torsional actuator is proposed by embedding helically wound fibers into a conjugated polymer tube during the polymer-deposition process. Upon actuation, the electrolyte-soaked tube swells, and consequently, produces torsion and other associated deformations because of fiber-induced mechanical anisotropy of the composite material. A nonlinear elasticity-based model is presented to capture the torsion, elongation, and dilation of the tube. Experiments on tubular actuators with different thicknesses, fiber-winding angles, and diameters confirm the aforementioned deformation modes and validate the effectiveness of the proposed model.

This paper introduces an alternative implementation of the traditional LC filter, called hybrid LC filter (HLCF). The construction described in this paper contains two foil windings that integrate inductance and capacitance into one unit. The main aspects of the HLCF design are considered. The experimental data show that the device proposed here can be used, instead of traditional LC filters, as an alternative solution for the mitigation of the adverse effects of the pulse-width modulation (PWM).

The objectives of this paper arise through the investigation of a motor with a high starting torque, although with limited intensities, weak intensity variations depending on the load, controlled losses in no-load tests, and an acceptable performance in steady state, and with a good response in transient periods. All these requirements would have to be obtained without the help of power electronics; in this way, the motor would be more robust, longer lasting, and without the need for auxiliary equipment. In this paper, the operation principle, the characteristic parameters, and the obtained results for the spiral sheet motor are analyzed for three speed regimes, namely, 1000, 1500, and 3000 r/min. In addition, the spiral sheet motor is compared with the squirrel cage rotor, the solid rotor with rings, the wound rotor with additional resistances in the rotor circuit, and the hollow diamagnetic rotor.

Plasma medicine is emerging worldwide, and some promising applications seem to be near the horizon. Direct therapeutic plasma application as the central field of plasma medicine will bring physical plasmas directly on or in a human (or animal) body. Campus PlasmaMed is a research association supported by the German Federal Ministry of Education and Research (BMBF), concentrated in the northeast of Germany and founded to explore promising and safe applications of atmospheric-pressure plasmas in medical therapy based on systematic and interdisciplinary basic research on the interactions of plasma components with living systems. Whereas a broad spectrum of plasma sources dedicated for biomedical applications has been reported during recent years, mainly two basic principles of plasma sources are used in the Campus PlasmaMed: atmospheric-pressure plasma jets and dielectric barrier discharges. A comprehensive assessment of potential risk factors, such as gas temperature, power transfer from plasma to the target, (V)UV radiation emission, or the generation of toxic gases and its release into the adjacencies, which could be dangerous for patients and therapists, has to be done as a basic precondition before any biomedical experiments can be started or a potential therapeutic application can be taken into consideration. Despite the fact that the initial plasma-source characterization and optimization are in the main responsibility of plasma physicists and engineers, potential users from the biomedical field should be integrated as soon as possible to include special needs and constraints for specific applications during early steps of development. This multidisciplinary research cooperation among plasma scientists and engineers on the one side and life scientists and clinicians on the other is one of the main characteristics of the Campus PlasmaMed. Such interdisciplinary cooperation is more than ever required for the characterization of biological effects of plasma sources, which has to be realized by a multistep program, starting with the investigations of plasma–liquid interactions and including a broad spectrum of in vitro tests with cells, as well as cell and tissue cultures up to isolated tissues or organs to be proved finally with animal experiments and clinical trials. Because there are no standardized criteria so far according to which atmospheric-pressure plasma sources can be assessed as to their suitability for medical applications, interdisciplinary results from plasma medical research have to be transferred into rules and standards to guarantee successful and safe practical application, including economic exploitation of plasma-medical research results.

With the widespread use of digital cameras, freehand wound imaging has become common practice in clinical settings. There is however still a demand for a practical tool for accurate wound healing assessment, combining dimensional measurements and tissue classification in a single user-friendly system. We achieved the first part of this objective by computing a 3-D model for wound measurements using uncalibrated vision techniques. We focus here on tissue classification from color and texture region descriptors computed after unsupervised segmentation. Due to perspective distortions, uncontrolled lighting conditions and view points, wound assessments vary significantly between patient examinations. The main contribution of this paper is to overcome this drawback with a multiview strategy for tissue classification, relying on a 3-D model onto which tissue labels are mapped and classification results merged. The experimental classification tests demonstrate that enhanced repeatability and robustness are obtained and that metric assessment is achieved through real area and volume measurements and wound outline extraction. This innovative tool is intended for use not only in therapeutic follow-up in hospitals but also for telemedicine purposes and clinical research, where repeatability and accuracy of wound assessment are critical.

This paper propounds a practice of using cut cores with a distributed air gap in the production of magnetic circuits for high quality medium voltage instrument transformers. It discusses utilization, for this purpose, of both grain-oriented and non-oriented electrical steel sheets of different grades, hence of considerably different characteristics and cost. The magnetic properties of the transformers were enhanced, and substantial technical and economical benefits in the manufacture of the end product were realized. [ABSTRACT FROM PUBLISHER]

A portable low temperature air plasma torch was used to control bleeding from wounds. As animal models, two pigs were used in the tests: one for the plasma treatment, and the other as the untreated control. Plasma effects on the bleeding times of three types of wounds (straight cut and cross cut in the ham area, and a hole in the saphenous vein of an ear) were examined. The results were that this plasma torch shortened the bleeding time for these three types of wounds from about 3 min to 18 s, about 4 min to 13 s, and 88 s to 15 s, respectively. Emission spectroscopy of the torch was performed to explore the reactive species carried by the plasma effluent of the torch. The results show that this torch carries abundant reactive atomic oxygen (RAO), which is the dominant reactive species in the plasma effluent. RAO can activate erythrocyte–platelet interactions to enhance blood coagulation for plug formation. The present tests indicate that RAO can also penetrate through the skin surrounding the wound to block capillary blood flow to the wound. [ABSTRACT FROM PUBLISHER]

Ceramic-silver composite conductors have been fabricated in lengths greater than 200 meters using both powder-in-tube and dip-coated methods. Progress has been made in conductor uniformity through control of process steps including powder packing, tape coating, deformation, and heat treatment. Critical current density (J/sub c/) in lengths up to 100 meters has been evaluated by measuring end to end current in coils, both pancake wound and solenoid wound. These coils were made using a wind-and-react technique. J/sub c/ values greater than 10/sup 5/ A/cm/sup 2/ have been attained over 17 m lengths of conductor in these coils in self field at 4.2 K. The magnetic field dependence of 4.2 K J/sub c/ in fields its high as 17 T will be reported for these coils. Microstructural factors affecting J/sub c/ are discussed. [ABSTRACT FROM PUBLISHER]

Long high critical current density Bi-2223/Ag tapes are required for the realization of cables and windings to be integrated in electric power devices. A cooperation agreement among CISE SpA, Europa Metalli and INFN, concerns the development of silver-sheathed multifilamentary Bi-2223/Ag tapes, over 100 meters long, produced by means of the Powder-In-Tube (PIT) technique. The Bi-2223/Ag tapes were thermomechanically processed and then wound into double pancakes by the React and Wind method. This article presents and discusses the electrical and magnetic characterization of the tapes, their degradation after winding as well as the performances of the pancakes tested after the final assembling.

Wires of Pb/sub 1-x/Sn/sub x/Mo/sub 6/S/sub 8/ (PSMS) using the powder-in-tube process have been carefully drawn and the critical current density J/sub c/ has been measured on small coils wound with wires of 1.5 meter in length in magnetic fields up to 24 tesla. At 1.9 K, we achieved an overall critical current density J/sub co/, exceeding slightly 100 A/mm/sup 2/ at 20 tesla and 63 A/mm/sup 2/ at 24 tesla. Below 18 tesla, we always observed an abrupt occurrence of the resistive state, indicating that in this region J/sub c/ is limited by local defects, generally located at the ends of the coil. Nevertheless, at 15 tesla and 4.2 K, J/sub c/ reaches 550 A/mm/sup 2/. These very good results are the consequence of a better choice of the materials forming the wire and of a full control of the synthesis of the PSMS powder, The analysis of the field dependence of J/sub c/ shows that the grains are well connected, but that the critical field B/sub c2/ is still too low at 4.2 K (31 tesla instead of 50 tesla). An optimization of the annealing conditions is expected to considerably increase J/sub c/ at high magnetic fields. [ABSTRACT FROM PUBLISHER]

Bi-2212/Ag tapes have been produced using a continuous dip coating and partial melt processing technique. The role of the annealing and melt processing temperatures on the microstructure and current-carrying properties of the tapes are reported. In particular, the effect of a pre-anneal heat treatment on the residual carbon content from the organic binder has been investigated, in order to improve critical currents. These results have been used to optimise the temperature profile of a multiple-zone tube furnace through which continuous melt processing of the tape is possible. Multiple metre lengths of superconducting tape have been produced and wound into coils. Critical currents of 8.3 A in statically processed tapes and 1.9 A in continuously processed tapes have been achieved at 77 K, zero field. [ABSTRACT FROM PUBLISHER]

Superconducting solenoids developed for the Fermilab Mu2e require an extended R&D on superconductor cables performance, working in strong field in the critical currents range. To test these cables, the Mu2e Cable Test Solenoid was designed and fabricated at Fermilab. The solenoid contains three coils (two Main coils, and one Test coil), connected in series. The Main coils are wound with the well known SSC NbTi cable. They are permanently attached to the solenoid top and bottom carbon steel flanges. The Test coil is replaceable, and meant to be installed between two Main coils. This coil can be wound with any superconductor cable which needs to be tested (the first Test coil was wound with RIKEN heavy aluminum stabilized NbTi cable). The cables cross section ratio in the Main Coils and the Test coil ensures operating of Main coils in the current ranges well below the critical value for their cable, while the Test coil always works near its critical current range. The solenoid design and some cable splicing issues are presented. [ABSTRACT FROM AUTHOR]
