  • Woven lattices offer a pathway to highly compliant and tunable mechanical metamaterials. Here, authors present a geometric design framework for woven lattices that encodes topology and compliance, allowing for arbitrary complexity and enabling programmable large-deformation and failure responses.

  • The potential of thermoelectric devices is typically hindered by heat stagnation and poor mechanical strength, which degrade their performance. Here, the authors demonstrate larger temperature gradients and higher mechanical strength by developing 3D core-shell architected thermoelectric devices.
