This study is to develop structures with the ability to convert a compression force into radial
extension or shear force, to increase power output through piezo shear mode. In this work, a …

This paper evaluates a novel design of a bridge shear-force structure used to transfer large
compressive loads into shear loads on the surface of a piezo disc. The wave/crinkle design …

We report the discovery of nonlinear Weyl normal modes in two-dimensional (2D)
mechanical lattices. These modes form a degenerate loop in the Brillouin zone, which is …
