This project will demonstrate the feasibility of using an array of wireless, passive, microwave acoustic sensors and accompanying interrogator system to monitor temperature and pressure in harsh environments encountered within a turboshaft rotorcraft engine. The proposed sensor technology is based… More

This project will demonstrate the performance of prototype wireless, passive microwave acoustic temperature sensors in a high temperature lab environment, including demonstration of stable operation at 650oC (1200oF) for more than 250 hours. The proposed sensor technology is based on patented… More

This project will advance wireless high temperature harsh environment microwave acoustic sensor technology, whose feasibility was demonstrated by Environetix in Phase I, into a technology readiness evaluation stage through extensive sensor testing in laboratory and engine testbed environments. The… More

A critical need exists for miniature, passive, wireless sensors that can be placed on rotating parts within aircraft turbine engines to perform health monitoring of key components. To meet these needs, this SBIR Phase II project focuses on developing and field testing a passive, wireless microwave… More
