Abstract

This review explores the intersection of tribology and dermatology, explicitly focusing on studying the human skin and drawing inspiration from natural systems. It investigates animal adaptations and their implications for biotribological applications, with examples such as the friction anisotropy and wear tolerance of snakeskin, the healing properties of fish skin and the lotus effect for reducing adhesion in biomedical devices. Understanding human skin presents challenges due to its complex structure and variability influenced by age, gender, race and environment. The paper discusses in vivo and ex vivo measurements, substitute models replicating human skin properties and contact mechanics considerations. It explores contact models, measurement methods and factors impacting skin friction, emphasising the interplay between adhesion and deformation components. Techniques such as atomic force microscopy and the colloidal probe technique provide insights into mechanical properties and molecular interactions. By comprehending the complexities of human skin and its tribological behaviour, researchers can develop innovative solutions in areas ranging from soft robotics to medical research and aerospace technology.
皮肤作为一个界面:理解皮肤学,仿生学和摩擦学的协同作用
这篇综述探讨了摩擦学和皮肤学的交叉,明确地集中在研究人类皮肤和从自然系统中汲取灵感。它研究了动物的适应性及其对生物摩擦学应用的影响,例如蛇皮的摩擦各向异性和耐磨性,鱼皮的愈合特性以及减少生物医学设备粘附的莲花效应。由于皮肤的复杂结构和受年龄、性别、种族和环境影响的可变性,对皮肤的理解面临挑战。本文讨论了体内和离体测量,复制人体皮肤特性的替代模型和接触力学考虑。它探讨了接触模型,测量方法和影响皮肤摩擦的因素,强调附着力和变形成分之间的相互作用。原子力显微镜和胶体探针技术等技术提供了对机械性能和分子相互作用的深入了解。通过了解人类皮肤的复杂性及其摩擦学行为,研究人员可以在从软机器人到医学研究和航空航天技术等领域开发创新的解决方案。
