文章分析了人体运动时膝关节运动模型，研发了一种电磁式动能能源收集装置．当人体行走时，通过可穿戴人体膝关节动能能源收集装置的不平转子机构捕获膝关节运动动能，转化为电能，经稳压升压处理后，为移动设备充电，实现从机械能到电能的转换．通过理论分析与实验验证，该装置在穿戴者以2 m/s的速度行走时，可捕获电能的平均功率达到2.3 W，证实该装置可在人体运动中，通过收集膝关节动能对移动设备供电．%The paper analyzes the human knee motion model and proposes an electromagnetic energy collecting device from human motion. When human body walks, the motion can be captured by the uneven rotor mechanism of the wearable human knee joint energy collecting device, and the energy is converted into electric energy. After voltage stabilizing and improving treatment, it can recharge mobile devices. The conversion from mechanical energy to electric energy is realized. Through theoretical analysis and experiments, when the wearer walks at a speed of 2m/s, the average electric energy captured can reach 2.3W. It proves that the research project can be powered by the kinetic energy of the knee joint in the human body movement.
