Abstract
We demonstrate the vibrational edge mode transfer on the dimer mechanical lattice consists of the Triangulated Cylindrical Origami. The configuration of our dimer lattice can be altered only by twisting the chain, and therefore it does not require any replacement of constituent unit cells. Such in-situ tunable lattice opens the bandgap in the wave dispersion relationships with emerging boundary mode. By twisting the chain excited at boundary mode frequency, our numerical simulation shows high transfer fidelity of the edge state through the lattice. The simple and efficient state transfer can be leveraged for energy manipulation in engineering applications.
