The application of surface acoustic wave (SAW) resonators as sensor elements for different physical parameters such as temperature, pressure, and force has been well-known for several years. The energy storage in the SAW and the direct conversion fro

The usage of SAW resonators as remote sensors is well known. Double resonator sensors for reducing disturbing influences from the radio channel as well as the separation of the sensor element from the SAW device into the matching network are already

This paper discusses SAW resonators. The SAW device consists of a piezoelectric substrate with a metalization. It is shown that the sytems langasite-Pt and gallium orthophosphate-Pt are able to fulfill the demands for a high temperature operation. An

SAW resonators are particularly suitable for passive wireless sensing because of the high Q factor. The returned sensor signal consists of a frequency shift and a change in the amplitude. To ensure a good performance, such passive systems have to be

The basic idea of this sensor is to integrate the capacitive or inductive sensing element into the matching network of the Antenna-SAW-Resonator-System. By changing the matching network the resonance frequency is shifted over a certain range. Two SAW

A novel MIT Direct Digitising Signal Measurement (DDSM) module has been developed aiming to replace the centralised NI PXI system and PC processing of the Cardiff Mk2 MIT system, thus offering potentially faster measurement cycles. The proposed modul
