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 piezo...

Zusammenfassung: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.
