2D antenna turns wifi signals into electricity

The video discusses a rectifying antenna, or rectenna, made from a thin molybdenum disulfide semiconductor. This device captures electromagnetic waves, like Wi-Fi, and converts them into direct current. It produces 40 microwatts of power from typical Wi-Fi signals, enough to power small devices. Early applications include flexible smartphones, wearable electronics, and medical implants. The rectenna's flexibility allows it to cover large areas, potentially wrapping around infrastructure like highways and bridges.
