Skin-attachable electronics have garnered considerable research attention in health monitoring and artificial intelligence domains, whereas susceptibility to electromagnetic interference (EMI), heat accumulation issues, and ultraviolet (UV)-induced aging problems pose significant constraints on their potential applications. Here, an ultra-elastic, highly breathable, and thermal-comfortable epidermal sensor with exceptional UV-EMI shielding performance and remarkable thermal conductivity is developed for high-fidelity monitoring of multiple human electrophysiological signals. Via filling the elastomeric microfibers with thermally conductive boron nitride nanoparticles and bridging the insulating fiber interfaces by plating Ag nanoparticles (NPs), an interwoven thermal conducting fiber network (0.72 W m⁻¹ K⁻¹) is constructed benefiting from the seamless thermal interfaces, facilitating unimpeded heat dissipation for comfort skin wearing. More excitingly, the elastomeric fiber substrates simultaneously achieve outstanding UV protection (UPF = 143.1) and EMI shielding (SE_T > 65, X-band) capabilities owing to the high electrical conductivity and surface plasmon resonance of Ag NPs. Furthermore, an electronic textile prepared by printing liquid metal on the UV-EMI shielding and thermally conductive nonwoven textile is finally utilized as an advanced epidermal sensor, which succeeds in monitoring different electrophysiological signals under vigorous electromagnetic interference. This research paves the way for developing protective and environmentally adaptive epidermal electronics for next-generation health regulation.

皮肤附着电子产品在健康监测和人工智能领域获得了相当多的研究关注，而易受电磁干扰（EMI）、热量积累问题和紫外线（UV）引起的老化问题对其潜在应用造成了重大限制。在这里，我们开发了一种超弹性、高透气性和热舒适性表皮传感器，具有卓越的 UV-EMI 屏蔽性能和卓越的导热性，用于对多种人体电生理信号进行高保真监测。通过用导热氮化硼纳米粒子填充弹性体微纤维并通过镀银纳米粒子（NP）桥接绝缘纤维界面，形成交织的导热纤维网络（0.72 W m ⁻¹ K ⁻¹ ）的构造得益于无缝热界面，有利于无阻碍的散热，使皮肤佩戴舒适。更令人兴奋的是，由于Ag NPs的高导电性和表面等离子体共振，弹性纤维基材同时实现了出色的紫外线防护（UPF = 143.1）和EMI屏蔽（SE _T > 65，X波段）能力。此外，在屏蔽UV-EMI的导热非织造织物上印刷液态金属制备的电子织物最终被用作先进的表皮传感器，成功地监测强​​烈电磁干扰下的不同电生理信号。这项研究为开发下一代健康调节保护性和环境适应性表皮电子学铺平了道路。
