Vibration Energy Harvesting System Based on Magnetically Controlled Shape Memory Alloy

Abstract:

Aiming at the problem that the generation power of the vibration generator is small, which is based on current electromechanical energy transducer materials, the conventional circuit could not meet the power supply requirement of the load. First of all, the principle of vibration energy harvesting is analyzed. Furthermore, a new vibration energy harvester based on magnetically controlled shape memory alloy (MSMA) is designed, which were introducing to the intelligent power circuit. The vibration energy harvester based on MSMA solved the problem of low electromagnetic signal change and less deformation that based on other intelligent materials. Last but not least, simulation results show that the new intelligent power circuit can harvest the output power and drive the load to work. Comparing with traditional harvesting circuit, it is superior with lower power consumption and higher efficiency of energy conversion and energy harvesting.
