Fig. 8: The experimental setup consists of the device actuation, response measurement, and data acquisition/processing sections.
From: Strong internal resonance in a nonlinear, asymmetric microbeam resonator
The device was driven with a piezoelectric shaker feeding by an AC voltage through a function generator inside a vacuum chamber. Laser Doppler Vibrometry was used to measure the vibratory response, and the obtained signals were sent to a signal processing program through a digital oscilloscope
