尽管软材料在从交通运输到生物医学的各个领域都得到了广泛的应用，但对其摩擦学性能背后的控制原理进行基础研究的机会仍然很大。在进行软质材料摩擦磨损的摩擦学研究中，最大的挑战之一是低模量，这就需要在实验摩擦学中广泛使用的方便和可接近的接触区域中施加低力。多年来，许多优秀且成熟的摩擦学仪器已经过优化，用于硬材料，但基本上不适用于软弹性体、水凝胶、组织和细胞等低模量材料。这种对软接触基本测量的迫切需求导致了仪器仪表领域的发展，摩擦学和流变学之间的联系更加紧密，使用光学显微镜对接触变形的原位研究增加，以及对摩擦和磨损的速率依赖效应的新模型。改进测量实际接触面积的能力，评估软界面的随时间响应，减少剪应力测量的不确定性对于软材料的摩擦测量至关重要。本文概述了软摩擦学领域最近的一些努力，着眼于在活细胞层上进行非破坏性实验，以促进与生物学和生物医学的更强相互作用。
Despite the ubiquitous use of soft materials in everything from transportation to biomedicine, there remain tremendous opportunities for fundamental studies on the governing principles behind their tribological performance. One of the greatest challenges in performing tribological studies of friction and wear on soft materials is the low modulus, which necessitates low forces for convenient and accessible contact areas widely used in experimental tribology. Many excellent and established tribological instruments that have been optimized over the years for use with hard materials are essentially unusable for low modulus materials like soft elastomers, hydrogels, tissues, and cells. This critical need for fundamental measurements of soft contacts has led to a growing field of instrumentation development, stronger connections between tribology and rheology, increased in situ studies of contact deformation using optical microscopy, and new models for rate-dependent effects on friction and wear. Improvements in the ability to measure the real area of contact, assess time-dependent responses of soft interfaces, and reduce uncertainty in shear stress measurements are critical for friction measurements on soft materials. Some recent efforts in soft tribology are outlined herein with an eye towards performing non-destructive experiments on living cell layers to foster stronger interactions with biology and biomedicine.
