Abstract

It is difficult to experimentally observe the influence of differences in individual skin properties of human fingers on tactile perceptions. During subjective experiments, many parameters, such as skin properties, the transmittance of nerve signals, and individual feelings are intricately mixed; therefore, it is difficult to identify which elements are affected and to what extent. It has not been determined how age-related changes in the stiffness of skin influence tactile perceptions. We developed a two-dimensional cross-section human fingertip finite element model based on previous studies. Then, we estimated the influence of age-related changes in skin stiffness on Merkel cells and tactile perceptions by using finite element analysis. Age-related changes in skin stiffness were described by changing skin material properties in the model. Simulations using a model involving the fingertip being contacted with a rigid flat plate or a 2-point indenter were performed. Using a rigid flat plate and standard skin material properties, the contact width between the finger pad and the object was 5 mm. Meanwhile, the width changed from 5 mm to 4 mm when using a model of age-related changes of skin. Using a rigid 2-point indenter, the difference in the peak-to-valley of the Mises distribution around the Merkel cells indicated 2-point discrimination. Besides, the difference decreased by approximately 43% with changes in skin stiffness. These results indicated that age-related changes in skin stiffness influenced tactile perceptions.

估计年龄相关的皮肤硬度变化对静态刺激触觉感知的影响
在实验上很难观察到人类手指个体皮肤特性的差异对触觉感知的影响。在主观实验中,许多参数,如皮肤特性,神经信号的透射率,和个人的感觉是复杂的混合;因此,很难确定哪些因素受到影响,影响程度如何。目前还不清楚皮肤硬度随年龄的变化是如何影响触觉的。在前人研究的基础上,建立了人体指尖二维截面有限元模型。然后,我们通过有限元分析估计了年龄相关的皮肤硬度变化对默克尔细胞和触觉感知的影响。年龄相关的皮肤硬度变化通过模型中皮肤材料属性的变化来描述。使用涉及指尖与刚性平板或两点压头接触的模型进行了模拟。使用刚性平板和标准皮肤材料属性,指垫与物体之间的接触宽度为5mm。同时,在使用年龄相关皮肤变化模型时,宽度从5毫米变为4毫米。使用刚性2点压头,在默克尔细胞周围的米塞斯分布的峰谷差异表明了2点歧视。此外,随着皮肤硬度的变化,差异减少了约43%。这些结果表明,与年龄相关的皮肤硬度变化会影响触觉感知。
