Although skin-like sensors that can simultaneously detect various physical stimuli are of fair importance in cutting-edge human-machine interaction, robotic, and healthcare applications, they still face challenges facile, scalable, cost-effective production using conventional active materials. The emerging two-dimensional transition metal carbide, Ti3C2Tx MXene, integrated with favorable thermoelectric properties, metallic-like conductivity, a hydrophilic surface, is promising for solving these problems. Herein, multifunctional designed to precisely distinguish temperature pressure without cross-talk by decorating elastic porous substrates MXene sheets. Because the combination conductive thermally insulating, elastic, substrate integrates efficient Seebeck piezoresistive effects, resultant sensor exhibits not only an ultralow detection limit (0.05 K), high signal-to-noise ratio, excellent cycling stability but also sensitivity, fast response time, outstanding durability detection. Based on impressive dual-mode sensing properties independent detections, multimode input terminal electronic skin created, exhibiting great potential robotic interaction applications. This work provides scalable fabrication tactile detecting distinguishing stimuli.

Abstract Biomimetic electronic skins (e‐skins) are widely used in wearables, smart prosthesis and soft robotics. However, multimodal e‐skins, especially those based on hydrogels, face multiple challenges for practical applications, involving multi‐sensing signal mutual interference, low breathability stretchability. Here, a breathable stretchable e‐skin with multilayer film microstructure is developed to achieve self‐calibrated sensing of any two three stimuli: strain, temperature, humidity, minimal crosstalk. Hydrogel fibers different shapes designed strain temperature modules, the hydrogel as humidity module. The exhibits impressive performance, including detection limit (0.03%), linearity (R 2 = 0.990), high‐temperature sensitivity (1.77%/°C), wide range (33–98% RH). Interestingly, due directional anisotropy shaped fibers, realizes directions. By introducing porous elastomer encapsulation membranes, wearing comfort attained, while high stretchability (100% strain) maintained. Furthermore, personalized human‐machine interaction system created by integrating wireless circuit realize real‐time gesture recognition, physiological signals monitoring, prosthesis.
