Published: March 26, 2025

Empowering intelligent robots with cognitive abilities that rival or even surpass those of humans is the key to enabling more complex and sophisticated interactions. Currently, most electronic skins (e-skins) perform excellently in distinguishing shallow object properties, but they still face significant challenges perceiving deeper properties. Here, inspired by multisensory integrated cognition echolocation tactility bats, a bionic bimodal active (BBAC) e-skin designed. This utilizes feature fusion machine learning methods evolve from passive perception advanced and, further, constructs enhanced material system based on multilayer perceptron. enables robotic hands BBAC achieve synergistic dielectric constant, softness, types 8 smooth surface objects through simple proximity contact action without strictly controlling test conditions, significantly surpassing ability humans.

Bioinspired Flexible Epidermal Electronics with Superior Gas Permeability and Unidirectional Water Transport Capability

Nano Letters, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 26, 2025

Epidermal electronics are extensively used in human-machine interfaces and wearable sensors. However, managing sweat gas permeability at the skin-device interface to ensure comfort prevent skin damage during prolonged use remains a key challenge. Inspired by fog collection mechanism of cactus spines trichomes, this work develops biomimetic, flexible epidermal electronic device with high unidirectional water transport capability. The exhibits excellent flexibility (Young's modulus: 0.02 MPa), breathability (electrode: 3551.63 g day-1 m-2, substrate: 3795.38 m-2), (1.09 s), antigravity (2.50 s). Notably, continuous sweating (5 h) extended wear (7 days), it demonstrates outstanding electromyography (EMG) signal acquisition, signal-to-noise ratio (SNR) approximately 58 times higher than that commercial electrodes. This offers promising potential for advancing high-performance, electronics.

Cross‐Scale Regulation of Coaxial Twisted Core‐Sheath Composite Yarn for Constructing Permeable Intelligent Fabric with Multiple Protection and Perception

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 27, 2025

Abstract Smart fabrics with health protection, motion monitoring, and perception capabilities effectively managed optimized human health, significantly promoting the development of smart health. However, it remains challenging to achieve multifunctional mechanical robustness required for use in multiple scenarios without destroying characteristics softness air permeability. Here, a cross‐scale regulation strategy is presented based on chemical coupling‐physical twisting develop multiscale twisted core‐shell structure yarn. Benefiting from strong interfacial interactions coaxial wrapping structure, multi‐component functional particles are highly stably integrated into yarn while achieving ultra‐high strength (≈0.662 GPa). The resulting fabric exhibits good impact resistance (attenuate > 40% force), superior permeability (387.37 mm s −1 ), excellent eletromagnetic interference (EMI) shielding (36.1 dB), IR thermal camouflage, high triboelectric output ( V oc ≈39.1 V), ability sensitively perceive environment safety monitor real‐time. This study addresses long‐lasting challenge balancing functionality comfort offers new perspective developing next‐generation advanced wearable protective fabrics.
