“…Several solutions involving an array of piezoelectric shunts have been proposed to damp vibration of plates. Resonant shunts [1,2] exhibit performance around the electrical resonance but a multimodal control would require the addition of several electrical resonances for each shunt, which would lead to an impractical number of components. Broadband wave attenuation can be obtained with negative capacitance circuits [3] but this solution requires an external power supply.…”

Multimodal vibration reduction can be obtained by coupling a mechanical structure to an electrical network approximating its modal properties. This strategy is applied to the control of a clamped plate with a 2D network of passive electrical components. The plate and the network are coupled through a periodic array of piezoelectric patches that enables the energy conversion. The network is experimentally implemented with inductors and transformers in order to create electrical resonances that present a spatial distribution approaching the first mode shapes of the plate. By tuning electrical resonances to mechanical ones, it becomes possible to introduce the equivalent of a tuned mass effect. This effect only occurs if the electrical and mechanical mode shapes are sufficiently close, which requires specific network topology and boundary conditions. Once the network is tuned, adding resistors introduces damping that can lead to a broadband vibration reduction of the plate. It is thus shown that a 2D control can be implemented with a purely passive solution, which could be of great interest for many embedded applications.

“…Based on this favorable property, periodic arrays of negative capacitance shunted piezoelectric patches were demonstrated numerically by employing a transfer matrix method to control the band gaps of a phononic beam [25]. By observing the link between shunted piezoelectric materials and periodically engineered phononic crystals and EMMs, several successful designs have been demonstrated for plate flexural wave attenuation using locally resonant shunts [26][27][28][29]. Both numerical and experimental results have shown that waves can be efficiently damped near the circuit resonant frequency and the tunability of wave band gap frequencies can be virtualized by circuit impedance adjustment.…”

Recent research activities in elastic metamaterials demonstrate a significant potential for subwavelength wave propagation control owing to their interior locally resonant mechanism. The growing technological developments in electro/magnetomechanical couplings of smart materials have introduced a controlling degree of freedom for passive elastic metamaterials. Active elastic metamaterials could allow for a fine control of material physical behavior and thereby induce new functional properties that cannot be produced by passive approaches. In this paper, two types of active elastic metamaterials with shunted piezoelectric materials and electrorheological elastomers are proposed. Theoretical analyses and numerical validations of the active elastic metamaterials with detailed microstructures are presented for designing adaptive applications in band gap structures and extraordinary waveguides. The active elastic metamaterial could provide a new design methodology for adaptive wave filters, high signal-to-noise sensors, and structural health monitoring applications.
