摘要: Abstract The purpose of this paper is to propose new means for harvesting energy using electrostrictive polymers. recent development polymers has generated opportunities high-strain actuators. At the current time, investigation polymer harvesting, or mechanical-to-electrical conversion, beginning show its potential application. objective work was study effect cellular polypropylene electrets after high-voltage corona poling on an polyurethane composite filled with 1 vol.% carbon black at a low applied voltage in order increase efficiency electromechanical conversion Theoretical analysis supported by experimental investigations showed that structure rendered it possible obtain harvested power up 13.93 nW electric field 0.4 V/μm and transverse strain 3% mechanical frequency 15 Hz. This represents 78.14% frequency. percentage very significant compared other structures. Finally, found use best way decrease polarization good harvesting.
