✦ Synopsis

In this paper a resistive based sensor is presented. The transducer is made of a rubber sample as compliant material with a graphite film spread on the whole surface as conductive material. An extensive experimental program was carried out in order to characterize the device. Both quasi-static and fully dynamic responses were measured by means of dedicated test rigs. Moreover, a neural network model of the sensor was developed in order to capture its transfer function. A good agreement was found between the sensor responses obtained by the experiments and these according to the numerical model.
