SenGenuity is involved in the development of passive surface acoustic wave (SAW) sensors and multi-sensor systems, enabling remote wireless sensing of temperature for demanding environments over wide temperature range. At the current time, SenGenuity utilizes proprietary approaches to produce passive solid-state SAW sensors that can be interrogated remotely using RF signals, and that respond with a signal that encodes both the sensor's identity and temperature measurements. Together with partners, SenGenuity is working on transceiver designs that are optimized given the SAW operating parameters, and implementing conventional and innovative wafer-level packaging approaches (for devices capable of withstanding extreme environments) for a complete wireless multi-sensor system.
