The intrinsic elastic resilience, fatigue resistance, and self-adhesion of human skin are highly desired merits. However, they challenging to combine into a single mechanoreceptive electronic for healthcare monitoring humanoid soft robots. We introduce an elastically resilient, crack-tolerant, amphibiously adhesive, strain-sensitive (ERCAS-skin) featuring hierarchical gradient design. ERCAS-skin has skin-like binary structure carbon nanotube-coated thermoplastic polyurethane nanofibrous scaffold embedded in cross-linking polydimethylsiloxane (PDMS) matrix. endows with mechanical compliance (Young's modulus 2.4 MPa) crack tolerance (fatigue threshold 1285 J m-2) through matrix-to-scaffold stress transfer. PDMS ensures not only high resilience (recovery 95%) but also strong wet adhesion (0.76 N cm-1) synergistic hydrophobic chain mobility effect. generation mechanism the nanotube enables sensitivity wide strain-sensing range. Owing its excellent capability, was utilized as self-adhesive strain sensor hand gesture recognition both air under water fatigue-free motion robotic fish monitoring.

For the need of direct contact with skin, electronic skins (E-skins) should not only fulfill electric functions, but also ensure comfort during wearing, including permeability, waterproofness, and easy removal. Herein, study has developed a self-adhesive, detach-on-demand, breathable, waterproof E-skin (PDSC) for motion sensing wearable by electrospinning styrene-isoprene block copolymer rubber carbon black nanosheets as layer liner copolymers N, N-dimethylacrylamide, n-octadecyl acrylate lauryl methacrylate adhesive layer. The high elasticity microfiber network structure endow PDSC good sensitivity linearity strain sensing. hydrophobic crystallizable ensures robust, waterproof, detaching-on-demand skin adhesion. Meanwhile, fiber enables air water permeability. integration functions endows great potential human activities both performances.

Abstract Skin‐like fibrous materials with water‐resistant and moisture‐permeable capabilities have played a pivotal role in human health economic development. However, most existing waterproof‐breathable nanofiber face daunting trade‐off dilemma of waterproofness breathability. Herein, novel biomimetic structured (purslane‐like) membranes are reported simultaneously improved breathability enabled by the situ incorporation unique polymeric nanosheets via synchronized electrospinning–electrospraying strategy based on polymer solutions. The electrospun polyamide endowed purslane‐like hierarchical rough micro/nano‐structures introducing electrosprayed fluorinated polyurethane to generate desirable superhydrophobicity. Meanwhile, stacking cavities triggered large diameter (micrometer scale) provide higher porosity more passageways transport moisture air efficiently. Benefiting from abundant superhydrophobic microchannels, resulting nanosheet‐embedded exhibit robust hydrostatic pressure 121 kPa high water vapor transmission rate 12.9 kg m −2 d −1 permeability 15.6 mm s . This for achieving structures can open opportunities development future advanced various applications.
