What this work contributes
The authors describe how electrical and length measurements realize micronewton forces with SI consistency. Comparisons between electrical and deadweight forces demonstrate a traceability route and motivate independent calibration of a candidate propulsion experiment.
Where the evidence stops
A nominal sensor resolution alone is not an uncertainty budget; the calibration geometry, capacitance gradient, alignment, and transfer procedure must be established for the actual apparatus.
