Abstract
The ethylene sensor is formed from a substrate with a gold thin film layer formed thereon. The substrate may be formed from soda-lime glass with a thickness of approximately 1.0 mm. Correspondingly, the gold layer may have a thickness of approximately 200 nm. The gold layer is divided into first and second regions or electrodes by a variable impedance channel containing KAuMgCaSiNaOas an ethylene selective material. The channel may be configured such that first and second sets of interdigitated gold fingers are defined in the first and second regions or electrodes, respectively. An ohmmeter is connected to the first and second regions to measure a resistance therebetween. A reference resistance is initially measured that is indicative of an absence of ethylene. Subsequent measurements of the resistance are compared against this reference resistance, with variations in the measured resistance indicating the presence of ethylene.
