通过高度精确的感知和感觉运动活动,人类触觉系统不断获取有关环境的信息。在接触点处的皮肤与被触摸表面之间的机械相互作用充当该触觉信息的来源。使用专用的自定义机器人平台,我们在四个不同方向(近端,远端,桡骨和尺骨)的切向滑动运动开始期间,以不同的法向力和切向速度,在手指和平面之间的接触区域成像皮肤变形。这个简单的触觉事件证明了复杂的力学。我们观察到的接触面积减少,而增加的切向力,并提出解释这种现象的非线性硬化的皮肤。变形的形状和幅度高度依赖于刺激方向。我们的结论是,复杂的,但高度图案化和可重复的,在这项研究中测量的变形是一个潜在的信息来源,为中枢神经系统,需要进一步的机械测量,以更好地了解触觉感知和运动性能。
Through highly precise perceptual and sensorimotor activities, the human tactile system continuously acquires information about the environment. Mechanical interactions between the skin at the point of contact and a touched surface serve as the source of this tactile information. Using a dedicated custom robotic platform, we imaged skin deformation at the contact area between the finger and a flat surface during the onset of tangential sliding movements in four different directions (proximal, distal, radial and ulnar) and with varying normal force and tangential speeds. This simple tactile event evidenced complex mechanics. We observed a reduction of the contact area while increasing the tangential force and proposed to explain this phenomenon by nonlinear stiffening of the skin. The deformation's shape and amplitude were highly dependent on stimulation direction. We conclude that the complex, but highly patterned and reproducible, deformations measured in this study are a potential source of information for the central nervous system and that further mechanical measurement are needed to better understand tactile perceptual and motor performances.
