Spontaneous High Piezoelectricity in Poly(vinylidene fluoride) Nanoribbons Produced by Iterative Thermal Size Reduction Technique

tilization of the unique material properties represented by flexi-ble, lightweight and biocompatible piezoelectric polymeric materials such as poly(vinylidene fluoride) (PVDF)1 and its copolymer poly(vinylidene fluoride trifluoro-ethylene) (PVDF-TrFE)2 is expected to bring on new horizons for sensor, actuator, and energy harvesting applications where piezo-electric ceramic materials have been em-ployed hitherto. A closer look into the applications of piezoelectricity including biosensing,3 energy generation,46 pressure sensing,7 high precision positioning,8 artifi-cialmuscle and skin9,10 reveals that thermall
