Abstract Electronic skin (e‐skin), which mimics the tactile perception as human skin, is of interest to advance robotics, prosthetics, and human‐machine interactions (HMI). However, construction artificial e‐skin with simulated function morphology recognition stimuli response remains challenging. Here, design a multifunctional self‐powered system based on whisker‐like magnetized micro‐cilia array (MMCA) underneath flexible coils reported. Owing excellent flexibility MMCA, adaptive bending can be produced according inputs or surface morphologies. With built‐in magnetic moments, MMCA deformation thus alters flux distribution, induces an electromotive force (voltage) in for pressure detection quantitative micro‐scaled 3D It shown that using distinct voltage intensities waveforms, optimized applied real‐time healthcare monitoring, Braille identification, reconstruction relief information. By customizing moment alignments one device further produce distinguishable signals build up multi‐commands efficient HMI, e.g., underwater Morse code communication. Along temperature tolerance environmental immunity, exhibits potential serve effective channel intelligent topology high‐capacity communications.

Abstract Triboelectric nanogenerators (TENGs), a promising energy harvesting technology for distributed power sources, faces inevitable issues regarding long‐term wear and durability. However, current low‐wear TENGs are impaired by lower performances due to low charge density. Here, both addressed using double supplement TENG (DCS‐TENG). Adding two friction brushes allows the DCS‐TENG achieve high surface density (76.5 µC m −2 ) (697.5 mW Hz –1 ), setting new record among previously reported TENGs. Moreover, device exhibits unprecedented durability with an attenuation of only 5% after continuous operation 110 h (3 960 000 cycles). Using customized management module, 3 × 7 hygrothermograph array, high‐power vehicle's radar accelerometer modules stably powered, demonstrating DCS‐TENG's strong electrical load capacity. This strategy provides facile effective path conjointly boost output TENGs, taking them next level practical applications.
