啮齿动物用它们的胡须（触须）进行触觉感知。我们的人造胡须遵循啮齿动物触须毛囊的基本设计。在人工触须的实验中，我们探索了基于主动触须的触觉感知，发现触须的偏转幅度或速度提供了目标物体的定位信息。基于这种定位方法，在不同的伸出角度的接触距离的集合可以区分具有不同曲率的圆形物体，或具有不同横向形状的物体，例如在某种程度上的立方体或圆柱体。此外，对于光滑表面的物体，单个触须的触须滑动可以检测垂直形状。两个或两个以上垂直叠加的晶须可以通过观察它们的偏转幅度的差异或偏转速度峰值的时移来识别垂直形状。研究结果可能会为啮齿动物如何利用胡须识别各种形状提供线索。
Rodents use their whiskers (vibrissae) for tactile perception. Our artificial whiskers follow the basic design of the follicle of rodent vibrissae. In experiments with the artificial whiskers, we have explored tactile perception based on active whisking, and found the deflection amplitude or velocity provides the localization information of a target obeject. Based on this localization approach, a collection of contact distances at varying protraction angles can discriminate round objects with a varying curvature, or objects with different lateral shapes, such as cubes or cylinders to some extent. In addition, the whisker slip of a single whisker can detect the vertical shape for a smooth surface of objects. Two or more whiskers stacked vertically can recognize the vertical shape by observing the difference of their deflection amplitudes or the time shift of deflection velocity peak. The results may provide a hint of how rodents recognize various shapes using their whiskers.
