  Topological mechanical metamaterials have been widely explored for their
boundary states, which can be robustly isolated or transported in a controlled
manner. However, such systems often require pre-configured design or complex
active actuation for wave manipulation. Here, we present the possibility of
in-situ transfer of topological boundary modes by leveraging the
reconfigurability intrinsic in twisted origami lattices. In particular, we
employ a dimer Kresling origami system consisting of unit cells with opposite
chirality, which couples longitudinal and rotational degrees of freedom in
elastic waves. The quasi-static twist imposed on the lattice alters the strain
landscape of the lattice, thus significantly affecting the wave dispersion
relations and the topology of the underling bands. This in turn facilitates an
efficient topological state transfer from one edge to the other. This simple
and practical approach of energy transfer in origami-inspired lattices can thus
inspire a new class of efficient energy manipulation devices.
