Abstract

Humans rely on their fingers to sense and interact with external environment. Understanding the tribological behavior between finger skin and object surface is crucial for various fields, including tactile perception, product appearance design, and electronic skin research. Quantitatively describing finger frictional behavior is always challenging, given the complex structure of the finger. In this study, the texture and sliding direction dependence of finger skin friction was quantified based on explicit mathematic models. The proposed double-layer model of finger skin effectively described the nonlinear elastic response of skin and predicted the scaling-law of effective elastic modulus with contact radius. Additionally, the skin friction model on textured surface considering adhesion and deformation factors was established. It revealed that adhesive term dominated finger friction behavior in daily life, and suggested that object texture size mainly influenced friction-induced vibrations rather than the average friction force. Combined with digital image correlation (DIC) technique, the effect of sliding direction on finger friction was analyzed. It was found that the anisotropy in finger friction was governed by the finger’s ratchet pawl structure, which also contributes to enhanced stick-slip vibrations in the distal sliding direction. The proposed friction models can offer valuable insights into the underlying mechanism of skin friction under various operating conditions, and can provide quantitative guidance for effectively encoding friction into haptics.

手指摩擦行为与纹理和滑动方向关系的实验和建模
人类依靠手指来感知外部环境并与之互动。了解手指皮肤与物体表面之间的摩擦行为对触觉感知、产品外观设计和电子皮肤研究等多个领域都至关重要。由于手指结构复杂,定量描述手指摩擦行为始终是一项挑战。本研究基于明确的数学模型对手指皮肤摩擦的纹理和滑动方向依赖性进行了量化。所提出的手指皮肤双层模型有效地描述了皮肤的非线性弹性响应,并预测了有效弹性模量随接触半径的缩放规律。此外,还建立了考虑粘附和变形因素的纹理表面皮肤摩擦模型。结果表明,日常生活中手指摩擦行为中粘附因素占主导地位,并认为物体纹理大小主要影响摩擦引起的振动,而不是平均摩擦力。结合数字图像相关(DIC)技术,分析了滑动方向对手指摩擦力的影响。结果发现,手指摩擦力的各向异性受手指棘轮棘爪结构的支配,这也是远端滑动方向粘滑振动增强的原因。所提出的摩擦模型可为了解各种操作条件下皮肤摩擦的基本机制提供有价值的见解,并可为有效地将摩擦编码到触觉技术中提供定量指导。
