Nanogenerators: Thermally Induced Strain‐Coupled Highly Stretchable and Sensitive Pyroelectric Nanogenerators (Adv. Energy Mater. 18/2015)

Abstract

In article number 1500704, Sang-Woo Kim and co-workers report the production of thermally induced, strain-coupled, highly stretchable, and sensitive pyroelectric nanogenerators using a different thermal expansion coefficient in the micropatterned poly(vinylidenefluoride-co-trifluoroethylene) [P(VDF-TrFE)] and polydimethyl-siloxane (PDMS) structures. This innovative structure couples piezoelectric and pyroelectric effects of P(VDF-TrFE) by applying thermal energy, which enhances the power-generating performance of the nanogenerator while maintaining high stretchability.
