Direct-Write Piezoelectric Nanogenerator

In this project, we have successfully demonstrated the capability of a direct-write piezoelectric Poly(vinylidene fluoride)(PVDF) nanogenerator using near-field electrospinning (NFES) for the first time. Repeated and consistent output voltage up to 30mV has been generated under an external strain of 0.092% from a single electrospun PVDF nanofiber. We believe this technology can open up unprecedented possibilities in the field of NEMS/MEMS to convert mechanical strain into electricity for energy harvesting to power nanodevices or strain-sensing applications.
