Design of Micro Electromagnetic Vibration Energy Harvester and Storage System Based on Human Motion

摘要：

According to Faradays law of electromagnetic induction,the electromagnetic vibration energy harvester can convert the mechanical vibration of human running or walking to electrical energy, the harvester output is through detection/rectification, two-stage of energy storage, stabilize voltage which is able to reach stable voltage of 4.2V,current of 355mA.The whole system doesnt need external power supply, the electromagnetic vibration energy harvester has produced two part the electric energy, a part used to storage, and another part provided power supply for circuit chips. Characteristic of the selected chip is low power and high stability. Analyzing the energy harvesters structure and principles, a basic electronic circuit for storing the electrical energy is also The amount of output electrical energy about energy harvester is controlled by magnetic field strength, amplitude and frequency of human movement.
