Present modern era of world (especially India) is dependent extremely on non-renewable source of energy such as thermal,nuclear energy to provide electricity for its natives, so It is clear that non-renewable energy sources do not support sustainable development. Therefore, the best solution is a renewable energy source, but it is very present in nature and some can be damaged, so you can choose a piezoelectric material. In the material, some charge is generated on the surface as a result of the application of mechanical stress. The effect charge is proportional to the mechanical load. This is called the direct piezoelectric effect. The material also shows this phenomenon in reverse and has a measurable charge in proportion to the applied electric field. We hope that our readers will learn the goal of generating future free energy from piezoelectric materials.
