![]() ![]() To make it as a complete circuit, two faces are connected together and current is passed through it. In working system, the crystal acts like a tiny battery with a positive charge on one face and a negative charge on the opposite face. Piezoelectricity (also called the piezoelectric effect) is the presence of an electrical potential across the sides of a crystal when mechanical stress is applied by squeezing it.

The output of two systems is compared for a single unit, and according to this comparison, the array of compression type system has been designed. The compression type piezoelectric system is excited by the force applied by the train, and cantilever beam type system is excited by the ground vibrations of the track. The lead zirconate titanate (PZT), which is one of the recent piezoelectric, which accumulates more charge on mechanical disturbance, is used in both the cases. These systems are suggested to be embedded on the railway track and attached to the rail tracks to produce the electrical output. The two piezoelectric systems used for analysis are compression type piezoelectric system and cantilever beam type piezoelectric system. In this paper, an analysis of two methods of harvesting the electrical power from the two different piezoelectric systems in railway traction system is carried out.
