The heart of this project is to find a way to use lost energies. In this case vibrations caused by machines or walking is a lost energy that need to be used. As low power
electronics and wireless technology starts to develop recently, it was necessary to think of new power sources that produce low power and easily to be harvested. The
harvesting of power from different sources started to become commonly used in the last years. With the time the power harvesting circuits will replace the normal finite
power supplies used. Piezoelectric material technology produced a new way that uses some of the energy being wasted or ignored in the surrounding, in this case vibration
energy that usually lost. Theses materials is already put in to use to harvest power; however, the power produced by these material is very small to be able to power most
electronic systems. The research made into this matter has always ended up with the need for methods to accumulate the produced power until an amount of enough energy is produced. At the end of this project the outcome should be a stable source of power to charge a mobile battery or a power ban
