Abstract

Blood glucose monitoring is vital for controlling the complications of diabetes. We propose a noninvasive blood glucose monitor featuring multi-sensor fusion, which functions well for rapid yet accurate blood glucose monitoring and screening of diabetes. The characteristic parameters of diabetics were extracted by applying one-factor analysis of variance, and a classification model was established via principal components analysis and discriminant analysis to identify whether the subjects suffer from diabetes. In light of the challenges for noninvasive blood glucose monitoring modelling brought by different pathogeneses, disease processes and complicated complications of different diabetics, the subjects were classified into different categories via unsupervised K-means clustering algorithm and modelled for each category separately for expanded coverage and improved accuracy. The accuracy was clinically evaluated in 254 volunteers with type II diabetes. The results in the Parkes error grid were as follows: 58.33% in Zone A, 39.43% in Zone B and 2.24% in Zone C, with a correlation coefficient of 0.69 and a root mean squared error of 2.67 mmol/L. In 2019, the monitor was certified by the National Medical Products Administration of China as the first Class III Medical Device.

Abstract

In this work, the industrial glass-glass module was developed using bifacial n-type solar cell. The passivation emitter and rear total diffusion cells (PERT) structure solar cell combined boron spin-on with POCl3 diffusion and double sides H-pattern screen printing metallization. With the assistance of the spin-on single side doping method, an average efficiency of 20% with 90% bifaciality was obtained in our laboratory, 6*10 cells bifacial glass-glass modules were fabricated in industrial line. The PID about 3.5% was obtained after 600 hrs under 85°C-85% humidity with a bias of -1000 V, while the LID was about 0.19% under the IEC standard of 60 kW·h/m2 illumination. As expected, power output gains of 15% on sand and 30% on snow were recorded for the glass-glass bifacial modules compared with mono-facial modules in our outdoor experiments.
