Passive wireless surface acoustic wave (SAW) strain sensors offer significant advantages over alternative well known sensing technologies and can enable sensing applications robustly in very harsh environments. The passive wireless operation of SAW sensors is especially relevant given there is a drive for more robust and diverse sensing technologies in more complex and high performance applications. Wireless passive dynamic SAW strain sensing has been realised and has enabled force measurement during CNC turning. This paper demonstrates the SAW performance alongside two state of the art Kistler sensing technologies designed for this application area. Direct analysis and investigation of both static and dynamic signals is important for establishing bench-mark performancemetrics and the operational bandwidth of the SAW system.
