Abstract

With the widespread adoption of the Internet of Things (IoT) and wireless devices, the traditional battery-powered model faces challenges such as short lifespan, heavy pollution, and high maintenance costs. Self-powered technology, which enables autonomous device operation by harvesting ambient energy, has emerged as a research hotspot in the field of sustainable energy. The piezoelectric-electromagnetic composite energy harvesting technology combines the piezoelectric effect with the principle of electromagnetic induction to efficiently capture low-frequency mechanical vibration energy, making it suitable for micro-energy supply in low-power devices such as mice. This paper explores the application mechanism of this technology in mice, analyzes its structural coupling, energy conversion, and multi-physical field synergistic effects, and proposes directions for optimized design, providing theoretical support for the development of self-powered systems for wireless peripherals.
