1. A fiber optic force sensing assembly, comprising:
a structural member defining a longitudinal axis and including a plurality of segments that are adjacent each other along the longitudinal axis, each of adjacent ones of the plurality of segments defining a gap therebetween;
a flexure bridging each gap, wherein the flexure defines a cross-section on a plane orthogonal to the longitudinal axis, the cross-section defining an area centroid, a first inertial axis and a second inertial axis being defined as passing through the area centroid, the second inertial axis being normal to the first inertial axis and intersecting the longitudinal axis of the structural member; and
a fiber optic coupled to the structural member.
