MIT’s new sensor can power itself without a battery

For decades, the limitations of batteries have constrained how and where we monitor critical infrastructure. Imagine a scenario where sensors embedded within a ship’s engine provide real-time data without cumbersome wires or battery replacements. This seemingly futuristic vision is one step closer to reality thanks to a groundbreaking advancement by researchers at MIT: the development of a completely self-powered sensor.

MIT researchers have developed a sensor that can harvest energy from its surroundings without needing a battery or a wired connection. This sensor could be used to monitor the performance and efficiency of machines in hard-to-reach places, such as inside a ship’s engine.
