Electrical Capacitance Tomography With Differential Sensor
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 ...
