Energy Harvesting Device Based on Magnetic Levitation Magnetic Spring and Friction Power Generation
摘要
Aiming at the wearing adaptability and comfort of energy harvesters, an energy harvesting device based on magnetic springs and friction power generation is designed to collect human movement energy. The effects of magnetic energy product, magnetization direction and winding height of permanent magnets on the performance of magnetic spring power generation were studied, the influence of friction position on friction power generation was studied, an energy management circuit was designed, and a wearable composite power supply system was made, which improved the adaptability of magnetic springs and friction power generation in the wearable field, and provided a reference for the application of energy harvesting technology in the wearable field.
