In view of the power supply problem of direct tire pressure monitoring system in automobile industry commonly at present, a generating electricity device was designed in which the core element was giant magnetostrictive material. In the device, its design principle was based on the magnetostrictive inverse effect. The device could provide power for automobile tire pressure monitoring system, thus the button battery power supply mode could be changed. Research result provides an effective method for solving the power supply issue of automobile tire pressure monitoring system and it plays a certain promoting role for realizing passivity method of automobile tire pressure monitoring system. Moreover, it provides a new way for giant magnetostrictive materials application.
