The battery life of a wireless mouse is a common pain point. But what if there were a way to harness energy from the mouse itself to recharge it? Let’s explore the possibilities of energy harvesting, focusing on two cutting-edge approaches: magnetic induction and the scroll wheel.
The Power of Potential: Harnessing Energy from Movement
The goal is a „self-charging” mouse, converting motion into electrical energy to recharge the batteries. We’ll delve into two promising methods:
- Magnetic Induction: A mouse pad made of a magnetic material, and the mouse itself containing strategically placed copper coils. As the mouse moves across the pad, the magnetic field generates electricity within the coils through electromagnetic induction.

Technical Challenges and Solutions
Both systems require very small generators, storage capacitors, and magnetic components. Optimizing both energy generation methods is crucial. Designing for durability is also necessary to prevent friction and wear.
- Miniaturization: Designing small generators that are efficient and reliable.
- Energy Conversion Efficiency: Optimizing both energy generation methods.
- Friction and Wear: Designing for durability is crucial.
How Might This Work?
- Magnetic Induction System:
- Magnetic mouse pad.
- Copper coils embedded within the mouse.
- A small capacitor or rechargeable battery to store energy.
- Voltage regulation would match the mouse’s power requirements.
