Patterned Aluminum/Polydimethylsiloxane-Laminated Film for a Solvent-Driven Soft Actuator with Programmable and Multistable Shape Morphing.

Recently, soft actuators capable of deforming in predictable ways under external stimuli have attracted increasing attention by showing great potential in emerging industries. However, limited efforts are being spent on the untethered actuators with multistable deformations. Also, there is a lack of mechanically guiding design principles for multistable structures.
