Abstract
The invention relates to the technical field of microsensors, in particular to a uniform-strain S-shaped sensor which comprises an elastic body, the side cross section of the elastic body is of an H-shaped structure, a hexagonal through hole is formed in the middle of the front face of the elastic body, and straight groove through holes are formed in the positions, located at the top and the bottom of the hexagonal through hole, of the front face of the elastic body. A hexagonal through hole is formed in the middle of the base, the two side edges of the hexagonal through hole are vertically distributed, the length of the two side edges of the hexagonal through hole is six millimeters, the lengths of the other four edges of the hexagonal through hole are consistent and are all three millimeters, and included angles formed by the twelve-millimeter edges of the two sides of the hexagonal through hole and the two adjacent edges of the hexagonal through hole are 100 degrees. The purpose of enabling the strain of a deformation area to be uniform can be achieved by adjusting the angle of the hexagon, and therefore the linear performance and the hysteresis performance of a product are improved. After improvement, the strain distribution becomes uniform compared with the original design.
