Abstract

In this study, we developed an advanced skin-like material by incorporating hyaluronic acid (HA) into polydimethylsiloxane (PDMS) to enhance its elasticity and stretchability. This combination also results in a 2.77-fold improvement in thermal conductivity due to the inclusion of hexagonal boron nitride (hBN). Furthermore, the elasticity of the material can be tailored by adjusting HA concentration during the synthesis process, simulating the mechanical properties of skin. To mitigate the surface stickiness caused by the HA solution, an etched mold was used during fabrication. The resulting skin-mimicking substrate offers a precise and sensitive platform for evaluating frictional and tactile variations in cosmetic applications. This enables a more accurate representation using recently developed sensory evaluation equipment. Overall, this innovative system not only provides artificial sensory experiences but also a time-and cost-efficient alternative to conventional clinical testing.

可拉伸，柔软，导热聚二甲基硅氧烷嵌入透明质酸用于人工触觉感官评价

在这项研究中，我们开发了一种先进的类皮肤材料，将透明质酸（HA）加入聚二甲基硅氧烷（PDMS）中，以提高其弹性和拉伸性。由于包含六方氮化硼（hBN），这种组合还导致导热性能提高2.77倍。此外，在合成过程中，可以通过调节HA浓度来定制材料的弹性，模拟皮肤的机械性能。为了减轻由HA溶液引起的表面粘性，在制造过程中使用了蚀刻模具。由此产生的皮肤模拟基质为评估化妆品应用中的摩擦和触觉变化提供了一个精确而敏感的平台。这使得使用最近开发的感官评估设备能够更准确地表示。总的来说，这个创新的系统不仅提供了人工感官体验，而且是传统临床测试的一种时间和成本效益的替代方案。

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
