THIN FILM SENSOR TECHNIQUES FOR THE. INTERFACES IN NEXT GENERATION AERO. Centre for Advanced Materials and Surface. University of Salfor Salfor UK. Submitted in partial fulfilment of the .
Different physical effects and different sensor materials such as silicon, ceramic or metal are used.
Especially in the case of measuring small forces, the use of conventional foil strain gauges is limited.
The measurement uncertainty rises by force shunts and is due to the polymer foils use as they are susceptible to moisture. The electrical and gas sensing properties of chemically deposited zinc oxide ( ZnO) films were investigated. Two activation energy values, 0. This is useful in examining the correlations between the loads occurring in the machining process and the subsequent material modifications of the workpiece. However thin film resistive micro . Based on piezo-resistive layers, pressure sensors could be implemented on the spot.
A wide range of applications could benefit from this. National Aeronautics and Space Administration. Glenn Research Center, Clevelan Ohio. Minimally intrusive in engines: sensor thickness.
Sensors and Electronics Branch. Advanced thin film sensor techniques that can provide accurate surface strain and temperature measurements are being developed at. These sensors are needed to provide minimally intrusive characterization of advanced materials (such as ceramics and composites) and . They feature all stainless steel wetted parts, a broad selection of electrical and pressure . Use of Different Sensing Materials and Deposition.

Abstract—The performances of metal oxide semiconducting materials used as gas-sensing detectors depend strongly . Platinum thinfilm sensors for space applications. Various piezoelectric thin films were tested during this research. Thin films were tested under various configurations with the instrumentation necessary for applying stimulation and measuring the transmitted response.
Analysis of various thin film piezoelectric ultrasonic transducer have been performed.
