Evidence of multimodal vibration damping using a single piezoelectric patch with a negative capacitance shunt

In this work, a piezoelectric patch shunted with a negative capacitance circuit has been used to simultaneously damp several modes of a square aluminum plate at low frequencies. The active nature of such electromechanical system leads to regions of instabilities in which the highest vibration attenu...
