Measuring method for sensors based on polymer nanocomposites and sensor based on polymer nanocomposites

Abstract

A measuring method for sensors based on polymer nanocomposites including selection of 3+ different frequencies, and subsequently measuring the impedances of the sensor at those different frequencies. Next, the impedances are analyzed to determine an impedance model. Finally, the parameter-identification module identifies an optimal measuring parameter based on the impedance model. The optimal measuring parameter has the highest degree of sensitivity and selectivity for excitation of the sensor. The optimal measuring parameter is used for real-time monitoring of the sensor response at one or more of the at least three different frequencies. Also disclosed is a nanocomposite sensor including electrically conductive nanoparticles in a polymer matrix. The nanoparticles are smaller than 130 nm in at least one dimension, and an electrode structure is in contact with the polymer nanocomposite sensor layer, wherein electrical signals generated by the sensor in response to applied stimuli are measured in the electrode structure.
