Herein, we have synthesized multitalented β crystallite prosperous and high dielectric ZnO/PVDF thin films via in situ process for energy harvesting and energy storing applications. The impregnation of the ZnO nanoparticles (NPs) in PVDF matrix has enhanced the electroactive β crystal nucleation (F(β) ~ 84% at 0.85 vol% doping) as well as piezoelectricity (d₃₃ ~ 50 pC/N at 50 Hz) and the dielectric value (~ 109 at 1.7 vol% loading) effectively. The nanogenerator, named as ZPENG and the self-charged photo-power bank (PPB) developed using the optimized supercilious piezoelectric and dielectric films have exhibited superiority in power generation (power density ~ 32.5 mW/cm³) and energy storage capability (~ 2000 F/) respectively that are highly impressive outputs compare to other similar prototype devices reported elsewhere till now. The realistic utilities of our fabricated ZPENG have been proved by light up 15 serially connected commercial blue light emitting diodes (LEDs) and charging capacitor (1 μF) in a small time span under repetitive finger impartation. The ZPENG is also shows continuous band like power generation under vibration occurred due to blood circulation in human body. The self-charged PPB is also able to power up blue LED that has confirmed its realistic applicability as a power source.

本文中，我们通过原位合成工艺合成了多才多艺的β微晶繁荣和高介电常数的ZnO / PVDF薄膜，用于能量收集和储能应用。在ZnO纳米颗粒（NP）的PVDF基体的浸渍增强了电活性β晶体成核（F（β）〜84％在0.85体积％掺杂）以及压电（d ₃₃在50赫兹〜50 PC / N）和介电值（在1.7体积％负载时约为109）。纳米发电机ZPENG和使用优化的超薄压电膜和介电膜开发的自充电光功率银行（PPB）在发电方面表现出优越性（功率密度约为32.5 mW / cm ^3））和储能能力（〜2000 F /），与迄今为止在其他地方报道的其他类似原型设备相比，它们的输出令人印象深刻。在反复手指施加的情况下，在短时间内点亮15个串联的商用蓝色发光二极管（LED）和充电电容器（1μF）证明了我们制造的ZPENG的实际实用性。ZPENG还显示了由于人体血液循环而在振动下产生连续带状能量的产生。自充电式PPB还能为蓝色LED供电，这已经证实了其作为电源的实际适用性。
