Abstract

This paper aims to present the calibration of a piezoresistive force sensitive sensor for the use in the gripping devices. A short review on existent sensors is presented, with information concerning the piezoresistive sensor functionality. The used calibration technique is presented in parallel to the hardware and software elements. Several test cases were developed in order to obtain the forces and the contact areas similar with the ones between the human fingers and different gripped objects. The differences between several sensors response and the accuracy on the forces applied in the range of 0.1 mN to 1 N were observed, allowing to obtain a whole surface mapping of the sensor response to the applied force, in a matrix touch pattern.
