Applications: It́s smaller than a penny, and it could just save your life

The demand for smaller, more highly selective sensors is on the rise, and the market is extremely competitive, in the ever-evolving world of wireless sensor technology. With an increased need to monitor and detect various pollutants in food packaging, water treatment and various products in health care, wireless sensors must overcome limitations such as size, sensitivity and cost. Sensors without a battery can be designed to measure 1 cm or less in diameter, which is smaller than a penny. GE Global Research has developed multidetection radio-frequency identification (RFID) sensing platform. According to GE Global Research, these sensors can detect trace concentrations of toxic gases such as industrial chemicals, volatile organic compounds and various chemicals in liquids. The sensor reader can obtain several varied responses that allow it to identify and measure individual chemicals in different mixtures and in variable conditions.
