Electronic skins can monitor minute physiological signal variations in the human and represent body’s state, showing an emerging trend for alternative medical diagnostics human–machine interfaces. In this study, we designed a bioinspired directional moisture-wicking electronic skin (DMWES) based on construction of heterogeneous fibrous membranes conductive MXene/CNTs electrospraying layer. Unidirectional moisture transfer was successfully realized by surface energy gradient push–pull effect via design distinct hydrophobic-hydrophilic difference, which spontaneously absorb sweat from skin. The DMWES membrane showed excellent comprehensive pressure sensing performance, high sensitivity (maximum 548.09 kPa−1), wide linear range, rapid response recovery time. addition, single-electrode triboelectric nanogenerator deliver areal power density 21.6 µW m−2 good cycling stability harvesting. Moreover, superior performance enabled all-range healthcare sensing, including accurate pulse monitoring, voice recognition, gait recognition. This work will help to boost development next-generation breathable applications AI, interaction, soft robots.

Abstract Incorporating zero‐energy‐input cooling technology into personal thermal management (PTM) systems is a promising solution for preventing heat‐related illnesses while reducing energy consumption. Although concepts passive radiative materials are proposed, achieving subambient performance providing good wearing comfort remains challenge. Here, moisture‐wicking nonwoven metafabric reported that assembles and evaporative heat dissipation to achieve high‐performance moisture management. This demonstrates excellent spectral‐selectivity (sunlight reflection of ≈92%, atmospheric window emissivity ≈97%) Janus wettability through large‐scale electrospinning hierarchical design, also inherits superior elasticity, air/moisture permeability fabric. Subambient temperature drops ≈6.5 °C (≈750 W m −2 solar intensity) stand‐alone observed. Thanks the effect (water evaporation rate 0.31 g h −1 water transport index 1220%) enables fast sweat, maximum generation 1 mL sweat can cool skin, thus excessive sweating risk after intense exercise. Additionally, be regulated by applying various strains (0–100%). The cost‐efficiency wearability provide an innovative way sustainable energy, smart textiles, wet applications.
