Abstract
In this paper, we proposed a method to measure the shapes of objects with a shear stress sensor comprising cantilevers arrayed in line and covered by silicon rubber. Our sensor system offers the detection of concavo-convex shapes by scanning the surface of the object once. In the detection experiment, we observed the minimum width of convex shape was 3 mm, and the minimum gap of concave shape was 17 mm. In addition, we demonstrated that various types of object shapes such as diagonal, circle and circular ring were detected by this method.
