Flexible Nanocomposite Generator Using PZT Nanorods and Ag Nanowires

This study presents a piezoelectric composite generator using PDMS polymer, PZT nanorods, and Ag nanowires. To enhance output power of the generator, we inserted the Ag NWs into the PDMS-PZT composite, which play very important roles in our generator: First, it enables the PZT NRs well distributed in PDMS polymer. Second, it is to reinforce the applied stress of the device by enhancing its flexibility. Finally, conduction paths formed by the Ag networks can reduce the internal resistance of the device. To assess these effects, we have compared and evaluated output voltage and current of four different generators.
