Abstract
A force sensor is provided for use with an instrument. Accordingly, the force sensor includes a beam and a set of half-bridges that are arranged on the surface of the beam. Two of the half-bridges include tension resistors, while the other two half-bridges compression resistors. The half-bridges are arranged on the beam surface such that redundant measurements of orthogonal components of a force imparted to the beam can be made using four different combinations of three of the half-bridges.
