Abstract
We develop and validate an analytical model in order to achieve large actuation deformation and high load-bearing capacity in a multistable dielectric elastomer actuator (DEA). We integrate patterned shape memory polymers (SMPs) and stretchable heaters with a 30 mm x 30 mm DEA to locally soften different SMP regions by 250 times during the actuation, allowing multiple a wide range of actuated shapes, and latching of those shapes. The model allows optimizing SMP thicknesses and other design parameters to offer the best trade-off between the actuation and the load-bearing.
