Description

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.

 

Value Proposition

The system:

•Generates a constant and steady power

•Generates a higher power density (~1 to 2 W/cm3) as compared to conventional techniques

•Supports power consumption for real-time data transmission

•Operates at a broader frequency range, making it suitable for diverse applications as compared to conventional techniques

•Comprises a magneto-static coupling between a high permeability coil and a hard magnet’s array to harvest energy from a tire’s rotational motion

•Overcomes the battery limitation of a tire pressure monitoring system

•Is additionally effective for providing power to multiple sensor networks and other electronic devices
