GE develop battery-free, wireless sensors

GE Global Research announced a battery-free, multi-detection radio-frequency identification (RFID) sensing platform that could enable a wide range of low cost wireless sensing products in healthcare, security, food packaging, water treatment and pollution prevention. GE's unique RFID sensors are built on traditional RFID tags.

These new RFID sensors use a conventional RFID tag, but are coated with a chemically or biologically sensitive film. The sensor reader can obtain several varied responses, which allows the sensor to identify and measure individual chemicals in different mixtures and variable conditions. GE's sensors can detect trace concentrations of toxic gases such as toxic industrial chemicals (TICs), volatile organic compounds (VOCs), and chemicals in liquids.
