    • Honeycomb Actuators Inspired by the Unfolding of Ice Plant Seed Capsules 

      Guiducci, Lorenzo; Razghandi, Khashayar; Bertinetti, Luca; Turcaud, Sébastien; Rüggeberg, Markus; Weaver, James C.; Fratzl, Peter; Burgert, Ingo; Dunlop, John W. C. (Public Library of Science, 2016)
      Plant hydro-actuated systems provide a rich source of inspiration for designing autonomously morphing devices. One such example, the pentagonal ice plant seed capsule, achieves complex mechanical actuation which is critically ...
