Sensatek propulsion technology INC. Proposes to demonstrate the feasibility of a wireless passive nanoparticle-based sensor system

The sensor in its current form can be used to measure real time temperatures and pressures wirelessly without the need of an external energy source. IT should be noted that the same sensing principle can be used for strain monitoring as well. IT comprises of a microwave-resonator-based sensor a microwave transceiver and a custom-made antenna. The microwave-resonator-based sensors uses a dielectric resonator structure a low-profile reflective patch temperature sensor and a pressure sensor based on evanescentmode resonator structure. These sensors are made of high-temperature-stable and corrosion-resistant ceramic materials which are suitable for extreme-environment applications. The use of nanoparticles can further reduce the size of the sensor enabling deployment in current hard-to-access areas. This approach will enable not only surface measurements of pressure and temperature but also provide in-flow measurements of gas path flows at cryogenic and high temperature environments. In-flow measurements within the metal piping of the fluid systems helps provide a dynamic and real time analysis of the operations of the system. Besides the embedded sensor helps in keeping the structural integrity of the component intact since IT s installation doesn t require machining pathways as is needed for traditional sensor cables. The proposed innovation will specifically provide the following benefits for propulsion system test development & flight applications: reduced cabling costs/time reduced auxiliary power requirements reduced weight penalties/operational costs associated with cabling and auxiliary power components remote real-time monitoring of component health flexible application due to low profile of sensor extreme environment measurement & survivability
