To meet the NASA need for measurement of pressure, temperature, and strain in high temperature and/or harsh environment to support rocket propulsion systems ground test, RC Integrated Systems LLC (RISL) proposes to develop a novel Hybrid Additive Manufacturing of Integrated Sensing (HAMIS) System, providing high-resolution simultaneous measurement of pressure, temperature, and strain in high temperature and/or radiation environment. HAMIS is based on additive manufacturing (AM) of passive wireless sensors using high-temperature refractory materials, capable of being bonded to the inner surface of high temperature gas pipes to measure temperature, pressure, and strain. HAMIS sensors can withstand temperatures up to 5000 degrees F.nbsp; AM approach enables flexible fabrication of miniature (4 mm by 4 mm by 0.8 mm) sensors. In Phase I, RISL will identify sensor types, number, placement, connectivity, and data handling and processing; determine processes and procedures for sensor manufacturing, insertion, and emplacement; demonstrate its feasibility through modeling; RISL will also develop a breadboard system to demonstrate the HAMIS concept. In Phase II, RISL will develop a HAMIS prototype with representative sensors of each type and test each under simulated laboratory conditions with the goal to achieve technology readiness level (TRL)-5.
