Abstract The development of highly stretchable self‐powered electronic skins with a broad detection range is urgently needed but remains great challenge. Herein, unprecedented stretchable, broad‐range‐response, supercapacitor‐type, one‐body, and are developed by assembling porous polyurethane/polypyrrole electrode, polyacrylic acid/polyacrylamide ionic gel electrolyte, polyurethane/MXene electrode. folded structure the electrodes significantly enhances stretchability, while modulus‐gradient multilayer device effectively broadens pressure range. combine dynamic/static sensing, ultrabroad (20 Pa–3.5 MPa), ultrahigh stretchability up to 387%, excellent compression stability (5000 cycles under 195 kPa), good stretching (500 200% tensile strain). They have capability monitoring human body motions, physiological signals, high pressures from motorcycle tires, as well tactile sensing robotic grippers. In addition, they can be applied for thermal management electromagnetic shielding devices. This work provides new strategy multifunctional wearable electronics sensors.

Triboelectric technology, with its renewable, low-cost, and eco-friendly advantages, offers new possibilities for intelligent motion-sensing equipment sports monitoring. We propose a maple leaf-based triboelectric nanogenerator (ML-TENG) green mechanical energy harvesting detecting table tennis corner kicks. The ML-TENG operates in contact-separation mode achieves peak power output of 63.38 W/m3 at an optimal load 50 MΩ. experimental results show transfer charge (Qsc) 35 nC, short-circuit current (Isc) 9 μA, open-circuit voltage (Voc) V. Tested ping-pong paddle, the generates consistent even under high-frequency impacts, demonstrating sensitivity to both strong weak forces.

Natural skin receptors use ions as signal carriers, while most of the developed artificial tactile sensors utilize electrons information carriers. To imitate biological ionic sensing behavior, here, we present a kind biomimetic, ionic, and fully passive mechanotransduction mechanism leveraging mechanical modulation interfacial p-n junction (IPNJ) through microchannels. Sensors based on this do not rely an external power supply can encode stimuli into highly analogous outputs to those natural receptors, in terms both type (i.e., potential difference) intensity (≈120 mV). More importantly, instant IPNJ regulation characteristic endows with superior performance when compared state-of-the-art piezoionic sensors, including low detection limit 0.01 N, fast response/recovery speeds (16 ms/16 ms), ultralow consumption (pW level), excellent reproducibility (over 100,000 cycles), good capabilities resolve static dynamic stimulations. As demonstrations, machine-learning-assisted high accuracy 99%) surface texture recognition object classification are successfully demonstrated integrated robotic hands. This work enriches family mechanisms provides path mimicking sensory systems for smart skins, prostheses, intelligent robots.
