l Main Contributions
- Dr. Yang has studied the piezoelectric energy harvesting technology for asphalt pavement. Combined with piezoelectric theory and pavement mechanics, designed and developed the piezoelectric energy harvester suitable for the pavement traffic load and analyzed the factors that affect the efficiency of piezoelectric power generation. Designed a self-powered synchronous charge extraction circuit to improve the efficiency of piezoelectric energy collection. Combined with the energy storage circuit and energy storage unit, formed a complete set of pavement piezoelectric energy collection system, which can convert part of the environmental dispersed unwanted vibration energy into useful electric energy. The collected energy can power the wireless acceleration sensor.
