1. Fragmented SHE design of e-skins for fine conformability.
Fragmented SHE design of e-skins for fine conformability. (A) Exploded view schematic illustration of e-skins. Inset images: Optical image (left) and corresponding surface strain field (right), evaluated by finite element analysis, of the unit SMD region. (B) Layout and functional description of the e-skin pair: controlling e-skin (left) and activating e-skin (right). Electronic functionalities for soft driving system, such as sensors, electronic control circuit and communication board, and actuating drivers, are spatially fragmented into two parts, providing wireless driving capability. (C) Photograph of the e-skin that wraps around the cylindrical rod (radius = 1 mm). The fragmented circuit configuration with the standard SMD dimensions (≤1.5 mm by 1.5 mm by 0.6 mm), and engineered pitch (≥2.3 mm) achieved the target deformation curvature (1/1.5 mm−1) in both outward and inward bending states (inset images) (see fig. S10 and note S1 for details on design criteria). (D) Extreme compliance of the e-skin that conforms to the corrugated surface (Al foil) with multiple curvatures.
