Light-powered RFID tags could soon power internet of things devices

MIT researchers have developed photovoltaic-powered sensors integrated into RFID tags, enabling them to function as energy harvesters. These sensors can operate in various light conditions and potentially last for extended periods, depending on environmental factors. The study, published in Advanced Functional Materials and IEEE Sensors, shows that these sensors can transmit data over longer distances than traditional RFID tags. This technology has potential applications in tracking cargo, monitoring soil, and managing energy use in buildings.
