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

Abstract

A model of a new class of total polymeric sensors known as ionic polymer–polymer composite <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$({\rm IP}^{2}{\rm C})$</tex></formula> 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 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">${\rm IP}^{2}{\rm Cs}$</tex> </formula> 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 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">${\rm IP}^{2}{\rm Cs}$</tex></formula> has been measured by means of the dynamic mechanical analysis and the results have been used in the identification of the <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">${\rm IP}^{2}{\rm Cs}$</tex></formula> 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.
