Thermally Induced Strain‐Coupled Highly Stretchable and Sensitive Pyroelectric Nanogenerators

Thermally induced strain-coupled highly stretchable and sensitive pyroelectric nano­generators are demonstrated using a different thermal expansion coefficient in the micropatterned poly(vinylidenefluoride-cotrifluoroethylene) (P(VDF-TrFE)) and polydimethyl-siloxane (PDMS) structures. When the piezoelectric and pyroelectric effects are coupled, the power-generating performance of the nanogenerator is dramatically enhanced with high stretchability. The highly sensitive pyroelectric nanogenerator operates with temperature changes ranging from extremely low to high.
