  • Continuous shape morphing for small robots can offer advantages, but it is difficult to perform tasks if they are not stiff enough. Xu et al. present here a design combining liquid crystal elastomers and shape memory polymers to lock morphable elements in place.

  • The authors make a bimodal network polyacrylate dielectric elastomer featuring high driving frequency like silicones and thereby a high power density of 154 W kg−1@20 MV m−1, 200 Hz. Their rotary motor realizes a maximum rotating speed of 1245 rpm@ 19.6 MV m−1.

  • Dielectric elastomer actuators (DEAs) with large electrically actuated strain can be used in non-magnetic motors, but high stiffness, poor strength and slow response currently limit the application of DEAs. Here, the authors optimize the crosslinking network in a polyacrylate elastomer to enable a DEA with high toughness and actuation strain and use the polyacrylate to build a motor which can be driven under low electric field.
