Implanted Devices Can Talk Through Wi-Fi

University of Washington (UW) engineers have introduced a new way of communicating that allows devices such as brain implants, contact lenses, and smaller wearable electronics to talk to everyday devices like smartphones and watches. This new “interscatter communication” works by converting Bluetooth signals into Wi-Fi transmissions over the air. Using only reflections, an interscatter device such as a smart contact lens converts Bluetooth signals from a smartwatch, for example, into Wi-Fi transmissions that can be picked up by a smartphone.
