Over Time

ABSTRACTA nickel micromechanical device was resonated and the natural frequency of the structure was monitored over time. Any structural rearrangement or damage initiation in the material was expected to cause a corresponding change in the resonant frequency of the device. The resonant frequency of the device was initially about 31.8 kHz and the frequency was found to decline over time at a rate of 0.17 Hz/s.
