Design of a self-diagnostic beam-mode piezoelectric accelerometerA technique was developed for detecting in situ real-time soft failures in a beam-mode piezoelectric accelerometer. The new technique can be used to detect changes in the piezoelectric capacitance, the equivalent mechanical stiffness of the piezoelectric element and the surface mounting impedance, and the piezoelectric efficiency.
