Milligram Mass Metrology Using Electrostatics

Abstract
Although mass has historically been defined using an artifact standard, other means of realization are possible. One alternative approach employs a precision electromechanical balance, using the SI electrical units to derive a force used to measure the weight of a mass artifact. The NIST Electrostatic Force Balance (EFB) incorporates SI-traceable voltage, displacement and capacitance measurements, allowing the traceable measurement of electrostatic force that can be used in conjunction with local gravity to arrive at mass. This article briefly describes this weighing process, its associated uncertainty, and context within the impending redefinition of the SI.Proceedings Title
