In Situ Performance Monitoring of Piezoelectric Sensors

NASA-Stennis Space Center, MS, United States

TECHNOLOGY SUMMARY

In-situ measurement system that monitors performance of piezoelectronic sensors/accelerometers, such as resonant frequency, response, cable status, connectivity, bonding and linear range. Tested in a wide frequency range, >200 MHz, in place without specially constructed transducers or wiring. Assessments are conducted with hand held test equipment or integrated into instrumentation systems.

Primary Application Area: Electronics, Sensors & Communications

Technology Development Status: Prototype

Technology Readiness Level: TRL 8

FIGURES OF MERIT

Value Proposition: Commercialize technology through partner licensing, provide benefits to marketplace. Design is somewhat a disruptive technology because it does not require the sensor to be removed from the test article for evaluation. Efforts to develop a bench top tester, field deployable test unit and facility installable test components are underway.
