Energy is one of the most important requirements for modern society.

The demand for electricity is increasing continuously in domestic, industrial, transportation, and communication fields. Due to this increasing demand, there is a need to develop alternative energy generation methods that are renewable, pollution-free, and capable of utilizing wasted energy.

In many systems, energy is wasted in the form of vibration, pressure, heat, and motion. Railway tracks experience continuous vibration and mechanical stress whenever a train passes over them. The vibration produced by train movement is normally unused. This project uses piezoelectric sensors to convert the vibration and pressure produced by train movement into electrical energy.

Piezoelectric materials have the special property of generating electrical voltage when mechanical pressure, vibration, or stress is applied to them. This property is known as the piezoelectric effect. By placing piezoelectric sensors at suitable positions near railway tracks or in a model track setup, the vibration energy produced by train movement can be converted into electrical energy.

The generated electrical energy can be rectified, filtered, stored in a battery or supercapacitor, and then used for low-power applications. This project is mainly designed to demonstrate the concept of energy harvesting from railway track vibration using piezoelectric technology.
