We present a low-cost fabrication technique of a polymer-based micro-opticalelectrical- mechanical systems (MOEMS) suited for the dynamic focusing of VCSELs (vertical-cavity surface-emitting lasers). A simple method based on an SU(8) double exposure is proposed for the collective integration of small footprint transparent suspended membrane arrays on vertical laser diodes. We demonstrate that this kind of MOEMS can provide under thermal actuation a vertical displacement of around 0.2 µmW-1 over a maximal range of 8 µm. As a wide range of initial gaps between the membrane and the laser source can be chosen, this approach opens new insights into the dynamic control of the VCSEL beam waist position as well as for tunable VCSEL fabrication.

Transdermal active drug delivery is one way to propose new disease treatment as an improvement to passive patches diffusion based on concentration gradient. Although skin limitations due to low permeability active transdermal delivery approach are investigated, by the proposition of an iontophoretic reusable and controllable patch. Making such an e-health care device offers active control and permanent actuating link able to control the amount of drug delivered. In vitro experiment is conducted to investigate the current effect on the permeation. Modelling and simulations are carried out to optimise the design and the electrical stimulation and finally a global overview of the architecture of the patch is presented. [ABSTRACT FROM AUTHOR]

The article discusses the use of Inertial Measurement Units (IMU) for real-time feedback for gesture sport performance monitoring particularly on swimming technique. The most common performance criterion for swimming is stroke length, stroke count and lap count and the tested device is a Swimbot. Topic includes methods for measurements which includes manual video analysis (VIRB cameras, Garmin, Schaffhausen) and motion capture system OptiTrack (NaturalPoint, Corvallis).
