Abstract : A sensor, having a sandwich configuration, is able to sense a transduce output parameter in situ without significantly affecting the parameter. The sensor comprises an inner sheet of a polymer having a transducer property. A conductive layer is deposited on parts of at least one of the two surfaces of the inner sheet. A pair of outer sheets of plastic are attached to each side of the inner sheet. Two layers of conductive material may be deposited on the outer, unattached, surfaces of the outer sheets, one layer on each surface. Keywords: Patents. (Js)
