Modeling of piezoelectric power nano-generators using Brownian particles

Abstract

We have designed a piezoelectric power nano-generator unitcell (device) where gas molecules are moving in Brownian motion and these molecules collide with a piezoelectric material. Due to the collision by gas molecules on the piezoelectric material, a voltage difference is induced across the piezoelectric material. We developed a simple model to calculate the voltage and power generation by using the method of statistical mechanics. Here we considered that gas molecules are not interacting with each other. We have created a design to connect nano-generator unitcells to form a chip in series configurations to enhance the production of the power nano-generation. Our design for the new power generator shows that as the thickness of the piezoelectric material increases so does the voltage generation. Our design can continuously generate electricity and this feature is better than solar panels that only work during daytime and windmills that cannot work without wind. It can work in a natural atmosphere environment. In the future when a new way of printing chips at low costs is discovered, then generating electricity will be very cheap using our design.
