(author), Gerhard, Reimund (author), Cao, Yang (author)Multi-layer ferroelectrets consisting of fluoroethylenepropylene (FEP) copolymer and open-porous expanded polytetrafluoroethylene (ePTFE) films exhibit stable internal electret charges, high piezoelectric coefficients and heat resistance, making them promising candidates for wearable sensors or nanogenerators in body-area networks. Here,...journal article 2024

Wang, Ningzhen (author), van Turnhout, J. (author), Daniels, Robert (author), Wu, Chao (author), Huo, Jindong (author), Gerhard, Reimund (author), Sotzing, Gregory (author), Cao, Yang (author)In contrast to molecular-dipole polymers, such as PVDF, ferroelectrets are a new class of flexible spatially heterogeneous piezoelectric polymers with closed or open voids that act as deformable macro-dipoles after charging. With a spectrum of manufacturing processes being developed to engineer the heterogeneous structures, ferroelectrets are...journal article 2022
