Published: March 25, 2024

Empowering robots with tactile perception and even thinking as well judgment capabilities similar to those of humans is an inevitable path for the development future robots. Here, we propose a biomimetic electronic skin (BES) that truly serves applies achieve superior dynamic-static material cognition functionalities. First, microstructured triboelectric piezoresistive layers are fabricated by facile template method followed selected self-polymerization treatment, enabling BES high sensitivity wide detection range. Further, through laminated-independent parts perceiving dynamic static pressures simultaneously, capable supporting robot hand monitor entire process during object grasping. Most importantly, further combining neural network model, intelligent system constructed real-time species via one touch under arbitrary pressures, which goes beyond human ability.

Continuous Rapid Fabrication of Ceramic Fiber Sponge Aerogels with High Thermomechanical Properties via a Green and Low-Cost Electrospinning Technique

ACS Nano, Journal Year: 2024, Volume and Issue: 18(29), P. 19054 - 19063

Published: July 8, 2024

Ceramic aerogel is an appealing fireproof and heat-insulation material, but synchronously improving its mechanical thermal properties a challenge. Moreover, the expensive discontinuous processing techniques inhibit large-scale fabrication of ceramic aerogels. Here, we propose water-based electrospinning method, based on hydrolysis condensation reactions precursor salts themselves, for continuous rapid (0.025 m

ABSTRACT Bimetallic nanoparticles (NPs) are recognized as effective catalysts for the nitrate reduction reaction (NO 3 – RR) to produce ammonia (NH ) due their multiple active sites and electron redistribution enabled by strong metal–metal interactions. An in‐depth analysis of mechanism is essential advancing efficient electrocatalysts. In this study, carbon‐supported Au Cu alloy (Au Cu/CC) were synthesized applied direct NO − NH . The generation rate achieved with Cu/CC was 1719.3 µg h −1 cm −2 , Faraday efficiency (FE) measured at 95.1% under an ultra‐low potential −0.5 V versus RHE. high activity attributed synergistic interactions between in relay catalysis, where exhibits selective *NO, while demonstrates excellent performance subsequent *NO Additionally, d–d orbital hybridization adjusts d–band center NPs, effectively modulating adsorption energies *N facilitate This electrocatalytic approach offers a novel strategy designing multifunctional RR catalysts.

Structure and Wiring Optimized TT/MT Double‐Helical Fiber Sensors: Fabrication and Applications in Human Motion Monitoring and Gesture Recognition

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 4, 2025

Abstract A fibrous flexible sensor, with its small size, minimally burdens the human body, ranking among most user‐friendly sensors. However, application is often limited by damage caused electrode movement, as sensors are typically attached to joints, which can be greatly alleviated placing two electrodes on same side. Inspired hydrogen bonds in double‐helical structure of DNA, design commonly found and applied fiber‐based batteries supercapacitors into through coaxial wet‐spinning further treatment. The double helical sensor exhibits high strength maintains stable operation prepared under over 300% strain gauge factors (GF) 0.9, 39.5, 349, respectively, working ranges.
