MIT's 2D antenna turns Wi-Fi signals into power TechSpot

Scientists from the Massachusetts Institute of Technology developed a 2D material that is based on existing rectifying antenna, or rectenna, devices. These capture AC electronic waves from the air and turn them into DC power. They tend to use silicon or gallium arsenide, making them rigid and suitable for powering...
