Electrodes were polished manually and electrochemically, followed by measurement of their roughness factor r from differential capacitance under 1 mM NaF [29, 30].
The thickness of PMPMS films was estimated from the differential capacitance per area, [C.sub.d], measured with electrochemical impedance spectroscopy (EIS).

SCM uses a metalized probe tip to bias the semiconductor in the depletion mode and to measure the differential capacitance between the probe and the semiconductor material as a function of the bias voltage [5-9] (see Fig.
The algorithm uses the doping sensitivity functions of the differential capacitance and uses a gradient-based iterative method to compute the locations of dopants from the experimental C-V curves.
MEMS accelerometers generally operate on a deflection principle, in which a mass deflects closer to or away from an electrode, causing a
differential capacitance, he said.
The resulting relationships between electrostatic potential and surface energy (electrocapillary curves), surface charge, and
differential capacitance are completely consistent with the traditional sharp-interface models of electrochemical interfaces.
Typical pressure sensor technologies include
differential capacitance, piezoresistive or resonant silicon.
