在这项研究中，开发了一种新型的“微 - 宏”平面微机电系统（MEMS）触觉传感器，它集成了两种不同尺度的触觉传感器，用于人工实现人类的指尖感觉。“微尺度”触觉传感器检测在人类指尖皮肤的指纹处产生和检测到的“微观表面形状”和“微小区域摩擦力”。另一方面，集成的“宏尺度”触觉传感器检测由指尖皮肤大面积检测到的“整体接触压力”和“大面积滑动摩擦”。由于“微观和宏观”触觉信息的结合在人类的指尖感觉中具有重要意义，这种触觉传感器可在样品表面的同一点同时实现多尺度触觉检测。它将成为理解人类如何利用指尖皮肤感觉识别物体的一个非常有力的工具。
In this study, a novel “micro-macro” planer MEMS tactile sensor integrating two different scales of tactile sensors has been developed for artificial realization of human's fingertip feeling. The “micro-scale” tactile sensor detects “micro surface shape” and “micro-area frictional force” that are generated and detected at a fingerprint on human's fingertip skin. On the other hand, the integrated “macro-scale” tactile sensor detects “overall contact pressure” and “macro-area sliding friction” that are detected by wide-area on fingertip skin. Since the combination of “micro and macro” tactile information has an important meaning in human's fingertip sensation, this tactile sensor realizes multi-scale tactile detection at the same time and at the same point on the sample surface. It will be a very powerful tool for understanding how humans recognize objects using their fingertip skin sensation.
