Abstract
Dielectric elastomer actuators (DEAs) are widely used in soft robotics because of their high energy density and intrinsic electromechanical coupling. Dielectric elastomer switches (DES) can complement DEAs by providing strain-dependent resistance modulation for simple logic and oscillatory circuits, but most reported DES rely on rigid supporting frames, which hinders their integration into fully soft systems. Here, we present a soft, frame-integrated architecture that unifies DEA actuation and strain-responsive switching. Inspired by inchworm locomotion, the DEA geometry was redesigned to enhance in-plane expansion and horizontal force output. A dual-layer PMMA frame guides membrane deformation and improves force efficiency compared with earlier configurations. Thin-film composite resistors were patterned and mechanically coupled to the deforming membrane; embedding them into frame openings enables reversible, synchronized switching during actuation. This approach provides a scalable pathway toward soft robotic systems with embedded actuation and on-body electrical readout for autonomous operation.
