Current energy sources for wearable health monitoring devices have disadvantages: power
So the researchers developed a broadband dipole antenna system that can wirelessly transmit data collected from health monitoring sensors.
The system consists of two stretchablemetal antennas embedded in metal-coated conductive graphene material. Next comes the rectifier circuit, which converts the energy of electromagnetic waves into electricity. It can be used to power wireless devices or to charge energy storage devices such as batteries and supercapacitors.
Energy can be obtained from radio orelectromagnetic waves that exist in the environment. Compared to other sources, less energy is generated, but the system operates continuously.
