- *Abstract
-
Currently, there is no known technology to harvest energy specifically for tire pressure monitoring systems. On the other hand, few general energy harvesting technologies have been developed for converting a mechanical energy into an electrical energy. Of these technologies, a method to harvest motion/vibration energy is one of the most commonly used. However, this method is associated with potential limitations such as narrow operating frequency range, limited applications and a low output power (in the range of mW/cm3). This novel approach enables the development and use of a wireless electromagnetic energy harvesting system for tire pressure monitoring on a real-time basis.
