ABSTRACT:
A load sensor includes a resilient member including a stationary segment, a load-receiving segment extending outward from the stationary segment, and an arm segment between the load-receiving segment and the stationary segment. Moreover, first and second strain-sensor elements are disposed on the same surface of the arm segment. The first strain-sensor element is adjacent to the load-receiving segment and the second strain-sensor element is adjacent to the stationary segment. The arm segment is tapered such that the cross-sectional area of the arm segment decreases from the stationary segment to the load-receiving segment. The narrowest portion of the arm segment has the first strain-sensor element disposed thereon. Accordingly, when a load generated by an impact is applied to the load-receiving segment, the maximum stress is reduced, and moreover, a difference between a stress applied to the first strain-sensor element and a stress applied to the second strain-sensor element is minimized.
