by Rebecca Walker — October 17, 2008—GE Global Research, the technology development arm of the General Electric Company, has 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 RFID sensors are built on traditional RFID tags.
This “first-of-its-kind” sensing platform, in which a single sensor can provide a highly selective response to multiple chemicals under variable conditions, operates without a battery, so sensors can be designed to be smaller than a penny and manufactured at very low cost.
This could enable many product applications, including new security sensors that more effectively can detect dangerous chemical and biological threats; in-the-field water purification monitoring; food and beverage safety monitoring; and emissions monitoring at power plants, says the company.
