Highly Efficient Piezoelectric Generation in Tyres

Abstract

This paper presents highly efficient Piezoelectric Generation in tyres with future scope and applications of its generation. This system is very much helpful for the battery operated vehicles as the concept involves the generation of electricity with the help of piezo material which are arranged in elastomeric belt of high strength placed in tire inner walls above the tire-to-road contact patch adjacent to the shoulder of tire. Piezoelectric material like Lead Zirconate Titanate (PZT) is employed for this purpose which is placed in inner walls of tires and experience sudden vibrations, bending of structures, when the tire rotates, which in turn according to the property of piezoelectric material generates electricity. This generation largely depends upon revolution of tire, amount of weight acting and proper placement of piezoelectric material.
