This paper presents a comprehensive study of the electromechanical behavior of PAAM hydrogel actuators. In this study, we developed a new method for the characterization of the pH gradient inside the gel actuator. Then we analyzed the volume variatio

This work presents a theoretical calculation of the I-V characteristics of an n-p junction. The total current across the n-p junction is presented as the superposition of currents due to each region of the junction. It results in ideality factor valu

The electrical properties of the drain–substrate diode of submicronic devices are shown to be related to the device geometrical structure. The analysis takes into account two-dimensional edge effects. Intrinsic parameters are extracted from current

Many brain computer interfaces (BCI) are based on feature selection from electroencephalogram (EEG) signals. To acquire these signals, a set of electrodes is used, most of the times attached to a brain cap. Several brain cap designs have been present

Polyacrylamide (PAAM) gels suits better the artificial muscle fabrication despite their response time which stays low compared to natural human muscle. This main problem is due to their bulky form where the ions exchange takes a long time compared to
