Abstract
Piezoelectric materials based on nanoporous polymer foams are provided. Also provided are nanogenerators incorporating the piezoelectric materials, piezoelectric energy harvesters incorporating the nanogenerators and methods of making and using the same. The piezoelectric materials comprise a unitary nanoporous matrix composed of a piezoelectrically active organic polymer, in which the pores are interconnected and have nanoscale diameters.
