Abstract

Here we report the design of a flexible piezoelectric-pyroelectric nanogenerator (PPNG) where both the active piezoelectric-pyroelectric component and the electrodes were composed of fiber. The active component was made with randomly oriented electrospun PVDF nano-fibers possessing electro-active β– phase. The PPNG exhibits outstanding electricity generation capability in combination with detecting temperature fluctuation. In addition, the piezoelectric and thermal energy harvesting ability of the PPNG paves the way for next generation thermal sensor and self-powered wearable electronics.Here we report the design of a flexible piezoelectric-pyroelectric nanogenerator (PPNG) where both the active piezoelectric-pyroelectric component and the electrodes were composed of fiber. The active component was made with randomly oriented electrospun PVDF nano-fibers possessing electro-active β– phase. The PPNG exhibits outstanding electricity generation capability in combination with detecting temperature fluctuation. In addition, the piezoelectric and thermal energy harvesting ability of the PPNG paves the way for next generation thermal sensor and self-powered wearable electronics.
