Rechargeable mice predominantly rely on battery power, necessitating long-lasting power sources. This paper proposes multiple vibrational energy harvesting systems featuring broad resonance bandwidths specifically for rechargeable mouse operations: clicks, swings, and scrolls. This approach captures increased electrical output continuously supplying lithium batteries via energy harvesting management circuits, thereby addressing battery longevity limitations. Simulation and experimental results confirm significant harvestable electrical energy for powering mouse batteries. At the resonance frequency, a wider bandwidth allows for the collection of more electrical energy. Furthermore, this structure is not only designed for mice, but the three-part energy collection system can collect more electrical energy to power the mouse battery.
