Tunable Buckled Beams with Mesoporous PVDF-TrFE/SWCNT Composite Film for Energy Harvesting.

ABSTRACT: By incorporating mesoporous piezoelectric materials and tuning mechanical boundary conditions a simple beam structure can significantly take advantage of limited mechanical displacements for energy harvesting. Specifically, we employed a mesoporous PVDF-TrFE composite thin film mixed with single-wall carbon nanotubes to improve the formation of the crystalline phase in this piezoelectric polymer. The film was then patterned on a thin buckled beam to form a compact energy harvester, which was used to study the effects of two boundary conditions, including the end rotation angle and the location of a mechanical stop along the beam. We carefully designed controlled experiments using mesoporous PVDF-TrFE film and PVDF-TrFE/SWCNT composite films, both of which were tested under two cases of bou
