| Abstract | In their article, ‘‘AC frequency characteristics of coplanar impedance sensors as design parameters’’, Hong et al.1 present an analytical model for the calculation of the resistance between two electrodes in a microchannel. However, their measurements fit poorly with their suggested model, and they attribute the discrepancies to electrode thickness and a ‘fringing effect’. In this note we show that the discrepancies are due to the neglected channel height in their model, and that by including two additional transformations, the resistance between two electro-des in a microchannel can be accurately modelled. The cell constant describes the proportionality between the resistivity of the medium in contact with two electrodes and the resulting resistance. The usefulness of the cell constant for microelectrode design optimization has been presented pre-viously.2,3 Both these papers treat sensor design for coplanar |
