${\rm{IP}}^{2}{\rm C}$ Sensor Modeling

A model of a new class of total polymeric sensors known as ionic polymer-polymer composite (IP²C) has been developed. Starting from a previous model, new experimental investigations have been performed in order to increase the significance of the sensor model. The device uses Clevios P HC V4 electrodes and a conducting polymer, produced and distributed by Heraeus. The sensing behavior of IP²Cs has been modeled by applying a suitable set of deforming signals and using a data-driven identification procedure. The sensor model has been investigated in a suitable range of working frequencies by using an ad hoc realized setup. Also, Young´s modulus of IP²Cs has been measured by means of the dynamic mechanical analysis and the results have been used in the identification of the IP²Cs sensor model. The model identification and validation have been performed by using a programmable mechanical vibration generator system, and experimental evidence of the suitability of the proposed model is given in this paper.
