Calibration of Force Sensitive Resistor used in Force Controlled Grippers

Abstract

This paper aims to present the calibration of a piezoresistive force sensitive sensors for the usage in gripping devices.A Force Sensitive Resistor(FSR) sensor is a device that allow measuring static and dynamic forces applied to contact surface.Their range of responses is basically depending on the variation of its electrical resistance. Studies have shown that the FSR sensors are usually applied for robotic grippers and for biomedical fields. This paper provides a brief overview of the application of FSR sensor as a feedback element for force controlled gripper.The used calibration technique is presented in parallel with the hardware and software elements. The results revealed that the FSR sensors are very useful devices that are able to provide a good contact force control, particularly for gripping.
