SYSTEM AND METHOD FOR GENERATING ELECTRICITY FROM MECHANICAL ENERGY OF ROTATING TIRE

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for generating electricity from a rotating tire at low cost without requiring addition of hardware.

SOLUTION: A tire assembly 10 comprising an integrated electricity generating device 14 is provided with more than one piezoelectric devices and a power regulating module. The piezoelectric device is installed on a tire or wheel assembly. Electric charges are produced when traveling on the ground to be accumulated in more than one energy accumulating devices. Accumulated energy is used for supplying electricity to electronic devices such as a tire monitoring system to send radio signals of information such as tire pressure, temperature, a discrimination variable, etc., to a receiver at a remote place.
