Develompment of flexible sensors based on piezoelectric nanofibers

This paper deals with the production of nanofibrous piezoelectric sensors for flexible applications. The nanofibers produced via electrospinning are integrated a soft hosting material (epoxy resin and polyurethane rubber) and the electrodes are manufactured by using conductive carbon powder. The process described in this work leads to the realization of a piezoelectric sensor suitable for flexible applications without any delamination risks or mechanical failures that could occur by using traditional piezoelectric films and metallic electrodes. The piezoelectric response results to be comparable with traditional piezoelectric devices.
