The shoe energy harvester used to collect all kinds of mechanical energy generated by foot movement and convert it into electric energy has great application prospects in wearable micro sensors, and has attracted extensive attention from domestic and foreign researchers. This paper systematically investigates the research progress of shoe energy harvesters at home and abroad. According to the different excitation generated by foot movement, shoe energy harvesters are divided into two types: direct loading type and inertia excitation type. The structure, working principle and advantages and disadvantages of these two types of energy harvesters are emphatically analyzed, and the development trends of shoe energy harvesters are summarized.
