Figure 1.

(a) Schematic of a bending unimorph dielectric elastomer actuator (left) and exploded view of the DEA device and different constituent material layers (right). (b) Schematic of depositing hydrogel on the surface of silicone-based layer treated with BP under UV light exposure. (c) Printing of the ionic hydrogel on the passive layer after surface treatment with BP and under UV light (left), final 3D printed DEA (middle), and SEM image of the DEA cross section (right). The green, blue, and white markers denote the passive layer, hydrogel electrodes, and dielectric layer, respectively.
