Description

technical field [0001] The invention belongs to the technical field of power generation devices and provides a road micro piezoelectric power generation device. Background technique [0002] Energy is the key to technological development. The development of major technologies in history is related to the utilization of new energy or the improvement of energy utilization methods. All human activities are inseparable from energy, and the development of society is based on energy consumption. With the depletion of environmental resources, the recovery and reuse of energy has been valued by the whole society. In recent years, the road mileage and the number of motor vehicles in my country have increased rapidly, and a large amount of mechanical vibration energy has been accumulated inside the road under the frequent action of vehicle loads. Therefore, the development of a power generation surface that can convert the mechanical strain energy inside the road into electrical en...
