ENERGY HARVESTING FROM ELECTROSPUN FIBERS AND PUSH-PULL LOW FREQUENCY ELECTRET TRANSDUCERS
Abstract
ENERGY HARVESTING FROM ELECTROSPUN FIBERS AND PUSH-PULL LOWFREQUENCY ELECTRET TRANSDUCERSPROJECT SUMMARYThis is a one year continuation project for N000141410570 with original project title~Development of Piezoelectric Polymer Composite Fibers for Energy Harvesting and AcousticTransducers.~ This one year proposal investigates two different electromechanical energyharvesting devices, one based on piezoelectric fibers patterned onto flexible substrate, and theother based on mono-charge electret placed in between electrode plate that can produce inductioncharges. For the piezoelectric fiber project, we plan to perform near field electrospinning (NFES)of poly(~-benzyl ~,L-glutamate) PBLG for the first time and directly deposit those fibers ontoflexible surface with patterned electrode for electric signal detection. We believe that PBLG willgive high piezoelectricity compared to conventional PVDF fibers due the parallel alignment ofpolymer axis and dipole direction during NFES. For the electret based device, we will construct apush-pull system where charged FEP Teflon film is placed in between two electrodes so that theup and down movement of the film can produce charges which can be collected using rectifiercircuit. Success of these two projects will pave ways for the development of new type of energyscavenging system for deployable autonomous sensors." - -
