摘要： A method for assessing the status of a piezoelectric sensor of interest 26, comprises the steps of 1) establishing a complex impedance profile expected to be exhibited by an acceptable sensor subjected to a test signal, 2) exciting the sensor of interest with a periodic excitation signal correlatable to the test signal, 3) analyzing the complex impedance of the excited sensor relative to the complex impedance profile, and 4) reaching a conclusion about the status of the sensor of interest based on the analysis. A system for carrying out an assessment of the status of a piezoelectric sensor of interest includes an analog signal source 32, a communication path 34 for placing the signal source in communication with the sensor of interest 26, means for digitizing a complex impedance exhibited by the excited sensor, and a processor 42 having access to a complex impedance profile representing an expected complex impedance of the excited sensor and also having access to an algorithm for analyzing digitized complex impedance relative to the complex impedance profile and for generating a status signal 48 responsive to the analysis.
