PDMS-ZNO Composite Textile Ferroelectret For Human Body Energy Harvesting

This research presents a flexible, low cost ferroelectret integrated into a piece of ordinary textile. The textile ferroelectret is made of PDMS (polydimethylsiloxane)-ZnO (Zinc oxide) nanoparticle mixture that spin cast on both side of a textile. The PDMS-ZnO textile ferroelectret achieved 55% piezoelectric coefficient d
₃₃
remaining, compared with 35% of pure PDMS textile ferroelectret. The measured piezoelectric coefficient d
₃₃
of the PDMS-ZnO textile ferroelectret is maintained at 220 pC/N after two weeks.
