The mode shapes of piezoelectric metamaterials are tuned by manipulating spatially the electrical boundary conditions of the piezo-elements. in a desired and controlled manner. in order to tailor the wave propagation characteristics through these metamaterials. The boundary conditions of the piezo-elements are controlled by using inductive shunting networks. https://www.ealisboa.com/limited-stock-Purple-House-Arrethe-Bush-Balm-Soap-quick-super/
