SURFACE-WAVE PASSIVE SENSOR INCLUDING AN INTEGRATED ANTENNA, AND MEDICAL APPLICATIONS USING SUCH A TYPE OF PASSIVE SENSOR

摘要

The invention relates to a remotely testable passive sensor that comprises an antenna and at least one surface-wave resonator (R, P, T) including a transducer with electrodes interdigited with two ports (p1 , p2) at the surface of a piezoelectric substrate (S), characterised in that the antenna includes conducting members (B1, B2) connected to the two ports and integrated onto said piezoelectric substrate. Advantageously, the antenna members are folded back onto the substrate in order to improve compactness. The passive sensor can be used in medical applications of the tissue-analysis of blood-pressure measurement types.
