ABSTRACT:
A method of powering one or more electronic devices in a tire monitoring system using a tire pressure based energy scavenger is provided. With this method, a tire is rotated on a surface to generate pressure changes within the tire. These pressure changes are then converted into electrical energy with a transducer and the energy is stored. The electrical energy or stored electrical energy can then be used to power one or more electronic devices in a tire monitoring system, such as a tire pressure sensor, temperature sensor, acceleration profile sensor, and/or a tire wear monitor. A tire monitoring system with a tire pressure based energy scavenger is also provided.
