The effective capacitance of the sensor, measured at 1MHz, increases with RH at room temperature. The RH sensing characteristics of PVA coated IDC transducer are analysed in terms of its sensitivity, dynamic range, frequency response, repeatability and recovery time. It is found that the stability of such a PVA based RH transducer improves remarkably by diffusing nanoparticles of CoFe<jats:sub>2<\/jats:sub>O<jats:sub>4<\/jats:sub> in the PVA layer. A standard deviation of \u00b1 0.05 and \u00b1 0.01 for a sensitive layer with pure PVA and PVA-CoFe<jats:sub>2<\/jats:sub>O<jats:sub>4<\/jats:sub> combination respectively results in a measurement
