（ BCTZ） is a lead-free piezoelectric ceramic with excellent piezoelectric properties and pollution free. BCTZ nanowires with pure perovskite structure are prepared by an electrospinning technique

and energy harvesting devices are fabricated by mixing with polydimethylsiloxane（ PDMS）. In order to improve the output performance of the device

dielectrophoresis is introduced to improve the orientation of nanowires in PDMS. The experimental results show that the maximum open circuit voltage and the maximum short circuit current of the devices after dielectrophoresis are 2.25 V and 27.3 n A

respectively. Furthermore

PDMS has good biocompatibility and ductility. The piezoelectric devices based on BCTZ/PDMS film have great potential in the wearable micro-nano electronic devices.
