A methodology for the prediction of chemocapacitor response due to the sorption of analyte without the need for fabrication of the actual devices is introduced. The methodology is based on experimental measurement of volume fraction due to sorption of the analyte through reflectance measurements and electromagnetic modeling for the InterDigitated Electrode (IDE) capacitor. The volume fraction and the capacitance of the device are coupled through the use of Clausius-Mossotti equation for the calculation of dielectric constant of sorbed polymeric film resulting in the prediction of the capacitance change due to the sorption of the analyte. © 2011 Published by Elsevier Ltd.
