Self-powered sensor automatically harvests magnetic energy
MIT researchers developed a battery-free sensor that harvests energy from its environment, designed for long-term data monitoring in inaccessible locations like ship engines. The sensor captures energy from magnetic fields around electric wires, operating without battery replacement or complex wiring. This innovation is beneficial in applications with limited power access.
The team overcame challenges, such as enabling the sensor to start without initial power " cold start " and efficient energy storage using capacitors. The microcontroller manages stored energy, simplifying installation and expanding deployment potential in various environments, offering more efficient and sustainable monitoring solutions in industrial settings.
