Abstract
We have designed and built a prototype electrostatic force balance for realizing forces in the micronewton range. The active electrodes are concentric cylinders, the outer serving as the reference and the inner suspended and guided by a rectilinear flexure mechanism. The geometry has been designed such that a near-linear capacitance gradient of 1 pF/mm is achieved at a working overlap of 5 mm. We have used this balance in a null displacement mode to compare an electric realization of force with the force generated by calibrated deadweights of nominal mass 1 mg, 10 mg, and 20 mg. The preliminary measurements reported here agree to within a few parts in 104 after including all known correction factors.Proceedings Title
