Fast response piezoceramic sensor with embedded microchip device development and testing is resulted. Sensor was designed for flow instability modes detection in gas-turbine engine passages by means of its outer casing vibration analysis. Main new features are analog to digital conversion by simple comparator and Haar wavelet analysis hardware implementation inside the sensor. These features in both allowed to reduce data flow without useful information lack and made possible utilization of simple, reliable 8-digit microchip. FORTH language is used for microchip programming.
