An international team of researchers has developed a way to harvest energy from radio waves to power wearable devices. The system consists of two stretchable metal antennas integrated onto a conductive graphene material with a metal coating. This system is connected to a stretchable rectifying circuit, creating a rectified antenna, or "rectenna," capable of converting energy from electromagnetic waves into electricity. This electricity can then be used to power wireless devices or to charge energy storage devices, such as batteries and supercapacitors.
