Getting rid of the wires and connectors in physiological monitoring
No Thumbnail Available
One of the main limitations towards an easy-to-use, comfortable, and reliable product for physiological monitoring comes from wires and associated connectors. Wireless solutions for data transmission are more and more common in every domain, but for biopotential and impedance measurements, at least one galvanic line will always be needed. This paper describes a new technology that can make possible the measurement of biopotentials and body impedances with high quality standard using only one wire. As this wire requires neither shield nor isolation, one can imagine a conductive garment that simply connects several sensors distributed over the body. From the user point of view, the product would be ‘cableless’.
