The piezoelectricity and the nanotechnologies – a possible future

Abstract

Starting by observing the mechanical phenomenon of tensioning – relaxing that repeatedly takes place within the surrounding environment (the example of a leave that moves due to the slightest breeze thus creating a tension into its tail) it has been analyzed the possibility of harvesting those tensions and turning them into electricity. As the idea was new but the phenomenon known for the last several decades (the transformation of mechanical work into electricity = the piezoelectricity and the piezoelectric effect) it has been identified the possibility of designing devices made of materials with known piezoelectric proprieties and adapting them to the original desired applications. The nanogenerators own characteristics so offer new opportunities having multiple field applications: medical, communications, auto industry, electronics, research and lab applications and last but not least the development of new materials, having usage within the construction industry.
