皮肤内的Pacinian小体是具有高灵敏度和宽感受野的机械感受器，并且它们有助于纹理评价和接触检测。它们少量分布在皮下组织中，这是皮肤的深层。我们提出了一个新的皮肤模型与纹理的胶原纤维，根据观察的拇指的aMacaca fuscata。使用该模型的有限元分析表明，胶原纤维分散应力集中在皮下组织中，导致广泛的Pacinian小体的感受野，同时保持其高灵敏度。
Pacinian corpuscles within the skin are mechanoreceptors with a high sensitivity and a broad receptive field, and they contribute to texture evaluation and contact detection. They are distributed in small numbers in the subcutaneous tissue, which is a deep layer in the skin. We propose a new skin model with texture of collagen fibers, based on observations of the thumb of aMacaca fuscata. A finite element analysis using the model reveals that collagen fibers disperse stress concentrations in the subcutaneous tissue, leading to a broad receptive field for Pacinian corpuscles while maintaining their high sensitivity.
