Abstract: An inspection method is provided during which a piezoelectric device is arranged with a specimen component of a powerplant. The arranging includes abutting the piezoelectric device against a surface of the specimen component. An electrical current is provided to the piezoelectric device at a (e.g., fixed) electrical voltage. The providing of the electrical current to the piezoelectric device energizes the piezoelectric device and induces vibrations in the component across a frequency range. The electrical current provided to the piezoelectric device during the energizing of the piezoelectric device and the inducing of the vibrations in the specimen component is monitored to determine a plurality of measured resonant frequencies of the specimen component within the frequency range. A measured resonance signature for the specimen component is determined based on the measured resonant frequencies of the specimen component.

Abstract: A piezoelectric sensor assembly for measuring a force quantity on a structure includes at least one piezoelectric sensor, each including an element and two electrodes each projecting outward from the element. An electronic processor of the assembly is configured to receive data from the sensor, wherein the data includes a voltage with a magnitude that is indicative of a dynamic load (i.e., amplitude modulation mode) placed upon the structure. The processor may be configured to interrogate the piezoelectric sensor for its resonant frequency change which is indicative of the load applied to the structure at low operation frequency and to which the piezoelectric sensor would not otherwise respond well. The dual mode operation of the piezoelectric sensor extends the frequency range of the strain measurement from the dynamic range to static or quasi-static range.
