GE has announced a new radio frequency identification (RFID) which can draw power wirelessly from an external reader. These RFIDs use traditional RFID tags with biological or chemically sensitive films, allowing many new potential applications. The new sensors could potentially be used to detect biological threats as well as check the freshness of foods in the grocery store. GE’s sensors are very small and will be able to be used in a wide variety of low cost uses. Passive RFIDs are nothing new, but the inclusion of the chemical and biological sensing ability allows for the possibility of RFIDs having a much greater prevalence in daily life.
