Abstract:Microelastic topological metamaterials (METMs) are of great use in the robust conveying and harvesting of high‐frequency ultrasonic energies. However, current METMs only hold topological edge states of a single flexural mode, restricting their capacity to convey ultrasonic energies of other polarized elastic waves. Moreover, the potential of METMs for ultrasonic energy harvesting remains unexplored. To address these challenges, an all‐polarized elastic topological metamaterial (AETM) is developed, capable of s… Show more
