Abstract Developing comfortable, protective, and reliable monitoring wearable devices is of great significance for next‐generation electronic devices. However, previously reported fabrics have proven inadequate cross‐mechanism sensing integration electromagnetic wave (EMW) protection. To address these, an wave‐absorbing flexible device with multimodal capabilities fabricated based on cotton fabric through polypyrrole (PPy) in situ growth as well dip‐coating polyaniline hollow microspheres (PHMs) amino silane modified polyurethane. It demonstrates excellent properties (Reflection loss peak: −48.20 dB, Effective absorption bandwidth:4.2 GHz). Remarkably, three units been all integrated by a principle (strain, temperature, triboelectric nanogenerator) all‐in‐one structural configuration. The motion unit shows quick response (225 ms) recovery (285 times high sensitivity (Gage factor ≈9.2). temperature has 0.59% K −1 . self‐powered tactile exhibits output voltage (41 V), maximum instantaneous power density (1.9 W m −2 ), detects touching incentive within 0.3 s. Smart human–machine interaction demonstrated applications like morse code, detection. This study serves proof‐of‐concept new smart textiles, showcasing potential devices, artificial intelligence, interactions.
