Touch Sensors for Safety in Industrial Automation Systems

This paper designs and evaluates a touch sensor based on a MOSFET that detects electric fields generated between mechanisms in industrial automation systems and human skin. The sensor aims to enhance safety in industrial operations. When the sensor installed on an automated mechanism comes into contact with human skin, it detects the electric field and electrostatic discharge. The processor immediately halts the automation or robotic system to ensure worker safety. The best test results indicate that the sensor operates with a response time of 3 milliseconds.
