Publication number: 20130046165Abstract: A system for a disposable capacitive bioimpedance sensor is used to collect bioimpedance data from an electric current traveling into or through an organism's tissue, where the bioimpedance data can be used to make medical analysis. The system mainly comprises at least one disposable sensor, at least one communication channel, a sensing circuit, and an instrument portion. The disposable sensor and the sensing circuit are used to retrieve the bioimpedance data from the organism's tissue, which is then sent to the instrument portion through the communication channel in order to be analyzed and processed. The disposable sensor includes a plurality of electrodes, an electrode support layer, and a capacitive signal receptor. The electrodes deliver the electrical current to the organism's tissue, and the capacitive signal receptor allows the electrical current to be properly sent or received through the organism's tissue. The electrode support layer holds the electrodes in place.Type: ApplicationFiled: August 17, 2012Publication date: February 21, 2013Inventors: David E. Cassidy, Him Shing Ng
