(RFID (Radio Frequency IDentification) A data collection technology that uses electronic tags for storing data. The tag, also known as an "electronic label," "transponder" or "code plate," is made up of an RFID chip attached to an antenna. ) 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 An electronic identification device that is made up of a chip and antenna. For reusable applications, it is typically embedded in a plastic housing, and for tracking shipments, it is usually part of a "smart" packaging label. . 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. GE's sensor technology overcomes limitations in today's sensors such as inadequate response selectivity selectivity /se·lec·tiv·i·ty/ (se-lek-tiv´i-te) in pharmacology, the degree to which a dose of a drug produces the desired effect in relation to adverse effects. selectivity 1. and the need for an on-board On board usually means to be traveling on some vehicle. For example, Baby On Board. Compare with overboard. Metaphorically, the term on-board is often used to refer to some piece of technology that is integrated in a moving vehicle, for example: * New security sensors that more effectively can detect dangerous chemical and biological threats * In-the-field water purification  It has been suggested that , , and be merged into this article or section. monitoring, checking for water

Epidemic over a wide geographic area. n. . * Emissions monitoring at power plants Radislav Potyrailo, a principal scientist at GE Global Research who leads this multidisciplinary wireless sensing development team, said, "We believe GE's battery-free wireless sensing platform will be a game-changer across many product platforms in healthcare, security, water and pollution prevention, to name a few. Without the need for batteries, we can make sensors that are much smaller in size and at substantially reduced costs. These attributes, combined with the sensors' highly selective chemical and bio sensing capabilities, provide new breakthrough sensing opportunities that will open the door to many new, innovative applications." Potyrailo added, "Because these sensors can be made at such low cost, they also can be made for one-time use. Similar to how your groceries get scanned for a price, imagine pointing a handheld sensor reader at a milk carton or packaged food to see whether it has been spoiled. This is just one of the new applications you can begin to consider with disposable, low cost multi-detection RFID sensors." 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 volatile organic compound Environment Any toxic cabon-based (organic) substance that easily become vapors or gases–eg, solvents–paint thinners, lacquer thinner, degreasers, dry cleaning fluids (VOCs), and chemicals in liquids. To operate without batteries, the power is obtained wirelessly from the sensor reader. The reader activates the sensor antenna and the RFID chip and collects several response data parameters. The measurement of these parameters provides the ability to selectively detect different chemicals with an individual sensor. The development of GE's novel wireless sensing platform illustrates the power of GE technology to leverage multiple areas of technical expertise from across many disciplines represented at GE's Global Research Center. A multidisciplinary team comprised of analytical chemists, RF engineers, polymer scientists, and microfabrication engineers contributed to the development of this new platform.
