Abstract
Disclosed herein are apparatuses and methods for measuring electrostatic charge on a surface of a substrate. The apparatuses comprise a substrate mounting platform, a substrate contacting component, and at least one voltage sensor, wherein the apparatus is programmed to independently control the rotational and translation velocity of a roller and/or to measure a voltage of the substrate at multiple points to produce a two-dimensional map of voltage for at least a portion of the substrate.
