passive sensor surface waves having an integrated antenna and medical applications using this type of passive sensor

A remotely interrogatable passive sensor comprising an antenna and at least one resonator surfaces (R, P, T) comprising an interdigitated electrodes transducer with two ports (p1, p2) on the surface of a substrate piezoelectric (S), characterized in that the antenna includes conductive elements (B1, 82) connected to both ports and integrated on said substrate piezoelectrique.Avantageusement the antenna elements are folded on the substrate to gain compacite.Le sensor liabilities can be used for medical analysis type of tissue or blood pressure measurement.
