According to foreign media reports, scientists have invented a machine that converts Wi-Fi signals into electricity and powers devices without batteries.
According to the researchers, this is a small, two-dimensional device powered only by passing Wi-Fi waves, which can be powered by Wi-Fi thanks to one of the advanced semiconductors that convert electrical signals into useful direct current.
Actually, making this conversion usually requires a device called a rectifier, but most traditional rectifiers are heavy and inflexible. MIT researchers solved this problem using molybdenum disulfide (MoS2).
Molybdenum disulfide is an ultrathin, malleable material, one of the thinnest semiconductors in the world, and it can be used to cover a fairly large area area, even walls or ceilings, with certain technological processes.
The team from MIT says that the device could power large electronic devices, wearables, and even medical devices, and that it could also be used for data communication in implantable medical devices, such as the development of a pill that can be swallowed by a patient and transmit health data back to a computer for diagnosis.
After all, if batteries were used to power these tiny devices, the damage to the organisms they are applied to would be enormous if they leaked.
