A MEMS-based system that enables low cost, low power, single chip realization of real-time signal detection and fault diagnosis. The system is suitable for analyzing the time-varying properties of a signal that are important for condition-based monitoring of electro-mechanical machines or structures. The system includes mechanical sensors that sense input signals such as vibration, signal templates of fault conditions, logic units that detect, store, and compare signal features to provide a diagnostic state, and an output readout mechanism to couple the diagnostic state to readout device that provides an external signal.
