Abstract

The simple DC electrometer, because of its low cost and simplicity, would be an ideal sensor with which to measure the electrostatic potential of charged surfaces, but all known DC electrometer configurations exhibit some degree of spacing sensitivity. For most practical applications, the spacing tolerance is so critical that AC or mechanically perturbed electrometer designs must he used at significantly greater cost.
