Abstract The recent surge of interest in electrostatic actuators, particularly for soft robotic applications, has placed increasing demands on high voltage control technology. In this respect, optoelectronic bidirectional switching and analogue regulation voltages is becoming increasingly important. One common problem the leakage current due to dark resistance material or device used. Another p...

In today’s multimedia orientated society, display devices used as man-to-machine interfaces to facilitate communication have become an indispensable part of daily life in both the public and industrial sectors. CRTs (cathode ray tubes) are the most widely used electric display devices because they provide a low cost, large screen, full-color image with high resolution, high brightness, and quic...
