Electrical Capacitance Tomography With Differential Sensor [PDF]
IEEE Sensors Journal, 2015 In electrical capacitance tomography, capacitance changes are used to determine the permittivity distribution in the imaging area. However, the changes are small compared to the standing capacitances, e.g. usually in the order of 10~30%. For a single channel capacitance sensor, a differential configuration having a redundant pair of electrodes can be ...

Evaluation of the differential capacitance for ferroelectric materials using either charge-based or energy-based expressions [PDF]
Journal of Advanced Dielectrics, 2014 Differential capacitance is derived based upon energy, charge or current considerations, and determined when it may go negative or positive. These alternative views of differential capacitances are analyzed, and the relationships between them are shown ...

The differential capacitance of magnetite
Surface Technology, 1979 Abstract Results from impedance measurements on a polycrystalline magnetite electrode in NaClO 4 solution are presented as plots of capacitance and resistance against potential. In order to explain the curves semiconductor properties of the electrode must be taken into account. Mott-Schottky plots indicate a change in semiconductor behaviour.
