Textiles based ferroelectret generator with enhanced energy harvesting performance

This paper presents a textiles based ferroelectret with enhanced energy harvesting performance by using a polymer with higher surface charge density and forming a optimize void structure. The textile ferroelectret is fabricated using a hot pressing process. The textile ferroelectret is made from two thin polyethylene terephthalate films and a thin layer of silk textile into a sandwich structure. Specifically, the ferroelectret generator, with piezoelectric coefficient d33 reaching 1600 pC/N, had worked stably for continuous about 10,000 cycles.
