What is it about?
This work describes a simple, cost-effective, flexible and scalable approach to fabricate an inorganic–organic hybrid nanogenerator. The poly(vinylidene fluoride–hexafluoropropylene) [P(VDF-HFP)] hybrid nanogenerator (HNG) is fabricated by casting a mixture of [P(VDF-HFP)] solution and ZnO nanoparticles (NPs) onto a flat surface, followed by HCl acid solution etching to remove ZnO. The peak value of the open-circuit voltage is found to be about 9.0 V under the repeating finger imparting. It has been demonstrated that the output power density of 7.58 μW/cm3 from HNG can drive several commercial light emitting diodes (LEDs) and able to charge capacitor that power up a calculator, indicating an effective means of energy harvesting power source for portable electric devices. This work demonstrated the practicability of using HNG to harvest large-scale mechanical energy, such as footsteps, finger tapping, bending, rolling wheels and hammer knocking etc.

Perspectives
Everyday, enormous amount of energies are wasted during walking, running, talking and so on. The way to capture and then use the energies in a scalable manner is very important as an alternate source of energy of fossil fuel. This work represents a simple approach to achive a high performance piezoelectric material to fabricate a nanogenerator which can be operated by single finger touch and other human motion to operate daily consumer electronics. Also, there is video proof of the demonstration. Though it was not uploaded but if anyone is interested then we can supply the video file of demonstration.
