Abstract
A tire pressure monitoring system (TPMS) having a self-powered sensing module having a sensor unit with at least one sensor for measuring at least one of a temperature, a pressure, and an acceleration in the tire, and a power unit generating a power by being deformed mechanically according to a rotation of the tire and supplying the sensor with a power required for actuating the sensor. The self-powered sensing module and the TPMS using the same are powered by the power unit generating the power owing to the mechanical deformation, without using a separate power supply. Hence, there is no need to replace a battery of the sensing module and maintenance costs are reduced.
