ASR&D Corp. is currently actively developing surface acoustic wave (SAW) sensors based on Orthogonal Frequency Control (OFC) saw technology. This technology development is supported by the following three NASA contracts:

NASA 2003 Phase II STTR NNK05OB31C: Passive wireless multi-sensor temperature and pressure sensing system using acoustic wave devices.  info

NASA 2005 Phase I STTR NNK060M24C: Passive wireless hydrogen sensors using orthogonal frequency coded acoustic wave devices. info 

NASA 2005 Phase I STTR NNK060M23C: Passive wireless cryogenic liquid level sensors using orthogonal frequency coded acoustic wave devices. info

More information on the core sensor device can be obtained from our Publications link.
