Additive Manufacturing of Integrated Sensor System

To meet the NASA need for measurement of pressure, temperature, strain and radiation in a high temperature and/or harsh environment to support rocket ground test, RC Integrated Systems LLC (RISL) proposes to develop a novel Additive Manufacturing of Integrated Sensor (AMIS) System, providing accurate simultaneous measurement of multiple parameters including pressure, temperature, and strain in high temperature and/or radiation environment. The AMIS is based on use of novel materials for high-temperature operation and uniquely designed fiber optic sensors. The AMIS sensors can tolerate operating temperatures up to 1800 degrees C and achieve measurement errors within 0.5% for temperature sensors and 0.2% for pressure and strain sensors. In mass production, each additive-manufactured microelectromechanical systems (MEMS) sensor will cost about $10. In Phase I RISL will demonstrate the feasibility of AMIS for in-situ measurement of temperature and strain by fabricating and testing a technology readiness level (TRL)-4 prototype, with the goal of achieving TRL-6 by the end of Phase II.
