US 9,518,882 B2 · Optical multi-axis force sensor

Abstract

A force sensor includes a rigid loaded member including a flat plate having a first major side, a second major side opposite the first major side, and a center; wherein the first major side and the second major side are substantially parallel to each other and to a plane including orthogonal X and Y axes, and are substantially perpendicular to the Z axis; at least two optical strain sensors directly secured to at least one of the first major side and the second major side; and an attachment means secured to the first major side substantially at the center; wherein the loaded member is configured to be securable to an associated supporting surface such that the second major side faces the associated supporting surface.
