“…For instance, electrometry is used in the areas of nuclear research [1] and even space exploration [2]. In one such example, electrometers were developed to evaluate the nature of electrostatic fields in Martian soil and atmosphere [3]. In addition, electrometry has also been used in mass spectrometry for chemical and biological analyses [4].…”

We have fabricated and demonstrated a micromachined electrometer with a charge resolution of 6 e/ √ Hz, operating at room temperature and ambient pressure. We thus show that high-resolution electrometry is realizable at room temperature and competitive with alternative low temperature (<10 K) solutions. The device presented in this paper functions as a modulated variable capacitor, wherein a dc charge to be measured is modulated and converted to an ac voltage output. By reviewing a selection of different devices based on this concept, we show that single-electron charge resolution at room temperature and ambient pressure is achievable with the aid of practical design considerations.

The surface charge generated on solid dielectrics placed in contact with granular materials at low gas pressures has been measured for several solid dielectrics. Induction sensors embedded in the dielectrics were used to measure the amount of charge that was induced on a metal electrode that had been exposed to some external distribution of electrostatic charge. These sensors have sensitivities in the picocoulomb per cmz range, achieved by adjusting circuit component values as well as the total electrode area Environments such as the one described for these experiments are encountered on the surface of Mars. These studies serve to characterize the response of different dielectrics to the Martian environment, with applications to the near future exploration of the planet
