Abstract
Summary: Surface acoustic wave sensors for industrial and biomedical applications Surface acoustic wave (SAW) devices are widely used as filters, resonators or delay lines in electronic systems for a wide range of applications such as mobile communication (cell phones), TVs, radar or stable resonators for clock generation . More recently, thanks to the sensitivity of the resonance frequency and the signal transmission delay to physical environmental parameters, the use of SAW devices has been expanded to measure gas concentrations, pressures, forces, temperatures, strains or radiations. SAW-based sensors have also the advantage of being passive (batteryless) and potentially remotely interrogated (wireless) In this talk, we will address the latest advances in SAW sensors with a focus on three main topics - Surface acoustic wave sensors for harsh industrial environments, especially at high temperatures - Magnetic SAW sensors - SAW sensors for biomedical applications, including “electronic tattoos”.
