Parallel double-plate capacitive proximity sensor modelling based on effective theory
AIP Advances, 2014 A semi-analytical model for a double-plate capacitive proximity sensor is presented according to the effective theory. Three physical models are established to derive the final equation of the sensor. Measured data are used to determine the coefficients.
