Researchers find material that turns Wi-Fi signal into energy

MIT researchers have made a discovery of new material that should help in bringing power to electronic and medical devices. The discovery consists of an apparatus that can pick up electromagnetic waves, such as Wi-Fi, and turn them into electricity.

According to MIT researchers, the device can convert alternating current electromagnetic waves into direct current waves, enabling the generation of electrical energy. This device created by the technology institute captures waves such as Wi-Fi signals as alternating current.

The idea is that the energy generated is enough to generate power for electronic circuits or to recharge batteries. This would allow devices without batteries to remain on at all times without plugging them in, which can be very useful in hospitals or patients who need medical equipment in their homes.

The MIT researchers commented that the device is flexible and can be manufactured so that it can cover a large area of ​​space to capture the waves. In tests, the device was able to produce 40 microwatts of power when exposed to common levels of Wi-Fi signals. This power is sufficient to operate an LED or turn on a silicon chip. For now, the device is still in the testing phase, not intended for public use.
