Application of piezoelectric transducer in energy harvesting in pavement

Mechanical energy appears everywhere in the nature. Road vibration energy created by the vehicle will not only do damage to pavement structure, but also is difficult to collect. Utilizing electromechanical conversion characteristics of piezoelectric material, one can gather the vibration energy when a vehicle is passing on the pavement and design the piezoelectric transducer package box, for traffic lights along the roads, signs, and so on. This will save the cost of laying long distance transmission line, and also take full advantage of the loss of energy. Experiments of piezoelectric boxes have been conducted in pavement to prove the effectiveness of this product. This study shows that utilizing piezoelectric technology in road energy harvesting is feasible and has a bright future.
