Abstract
This study presents an analysis of electrode patterns suitable for use with drop coated conducting polymer gas sensors. A thin-film technique was used to efficiently fabricate the copper electrode patterns [1]. Conducting Polymer Composite (CPC) materials were deposited using a 500 nano-litre syringe onto the electrode patterns to produce an array of sensors for organic solvent vapour detection. The sensors were exposed to propanol vapour in steps of 3000 ppm from a minimum concentration of 5000 ppm up to a maximum concentration of 20,000 ppm. Empirical results showed that a nonparallel electrode configuration produces a marginally larger responce and is also less noisy than the interdigitated or parallel electrode configurations. Results show that incresing the baseline resistance of the sensing material gives a larger responce.
