Telemetric surface acoustic wave sensor for humidity Faculty for Computer Science, Electrical Engineering and Mathematics, Sensor Technology Department, University of Paderborn, Warburger Str. 100, 33098 Paderborn, Germany Abstract. Surface acoustic wave sensors consist of a piezoelectric substrate with metal interdigital transducers (IDT) on top. The acoustic waves are generated on the surface of the substrate by a radio wave, as it is well known in band pass filters. The devices can be used as wireless telemetric sensors for temperature and humidity, transmitting the sensed signal as a shift of the sensor’s resonance frequency.
