Abstract
Provided is a small piezoelectric power generator applied to a wireless sensor network system of a tire pressure monitoring system (TPMS) for monitoring an internal environment of a tire such as variation in air pressure in the tire. In particular, when the system, in which air pressure, temperature and acceleration sensors are mounted, installed in the tire is operated in the TPMS for an automobile, a small piezoelectric power generator for the TPMS can be used as a power source in place of a conventional battery. The piezoelectric power generator includes a substrate having an electrode for transmitting power to the exterior, a metal plate formed on the substrate, and a piezoelectric body disposed on the metal plate and transmitting the power generated by a piezoelectric material to the electrode.
