Highly Sensitive Piezoelectric Ceramic Nanofibers for Flexible Transducers and Advanced Applications

Polymeric piezoelectric materials have attracted enormous success in the field of wearable electronics due to their high flexibility and good mechanical stability. Nonetheless, these materials exhibit a low piezoelectric response if compared to ceramics. This study is focused on the development of a flexible and highly sensitive piezoelectric sensor made with ceramic lead zirconate titanate (PZT) nanofibers. Results show an exceptionally high sensitivity of 30 mV/N and a piezoelectric strain coefficient d33 of 39 pC/N for the fabricated PZT sensor.
