Title: Robust Strain Sensor for Engine Monitoring and Control
Agency / Branch: DOD / DARPA
Contract: N/A
Award Amount: $104,332.00


As we approach the 21st century, increases in traffic accidents, the creeping paralysis of traffic congestion, and global environmental pollution have focused attention on reconciling the internal combustion engine (ICE) powered vehicle with the needs of the greater society. The solutions to these complex problems require the proper infrastructure and improved electronics technology to bring the ICE powered vehicle fully into the information era. This will require employing artificial intelligence to link the various control subsystems into an intelligent entity. One of the enabling technologies for this process is improved miniature distributed engine sensing subsystems. Deployment of intelligently coordinated sensor subsystems will substantially improve performance of ICE'S. Reliable, low cost, high performance miniature pressure sensors are a critically needed component for a wide range of future ICE systems. DOD has a need for robust embedded sensor technology for monitoring and control of internal combustion engines. We propose a novel robust strain sensor suited for the harsh ICE environment. The proposed sensor is rugged, compact and readily integrated into various components of an intelligent ICE control system. The Phase II program will implement an instrumented engine test bed with a neural network controller for integrating the outputs of several sensor subsystems. Anticipated Benefits/Potential Applications - The major advantages are the low cost robust strain sensor design, high sensitivity and high temperature capability. The robustness of the sensor will permit direct incorporation into applications on chassis or incorporation into power train components. The strain sensor will also find applicability on gas turbine engines used in military and commercial aircraft.
