ABSTRACT:
A power supply using a static magnetic field of a tire pressure monitoring system is provided. The power supply includes: a static magnetic field generator installed at a car position adjacent to a tire, and generating the static magnetic field; and an EMF (ElectroMotive Force) coil installed at the tire, and generating an induced electromotive force by the generated static magnetic field and a relative motion resulting from rotation of the tire, and providing the generated electromotive force to the transmitter and the sensor.
