FLEXIBLE ROBOTIC ELECTRONIC SKIN WITH HIGH SENSITIVITY SENSOR ARRAYS

In this paper, we propose a flexible robotic electronic skin (e-skin) with high sensitivity sensor arrays. The sensor arrays are designed and fabricated on thin flexible silicone film. It uses piezo-resistive material Samarian Monosulphide and graphite rods for interconnection between the layers. Along with the pressure sensing capability of SmS, temperature and humidity sensors are also integrated in the silicone layers along with photovoltaic thin layer cells that provide energy independence to the module. The data procured from the e-skin is transferred to the analog to digital converter unit and further, to the PC through USB interface for analysis.
