Abstract

A two-dimensional gas sensor with distributed response characteristics was fabricated by depositing silver in a pattern on an AuNPs substrate, and a method to estimate multiple mixed gas concentrations using the fabricated substrate was proposed. We also proposed a method to estimate multiple gas concentrations using the fabricated substrates with linear analysis. The gas concentrations were calculated using the different response characteristics distributed on the fabricated Au/AgNPs LSPR (Localized Surface Plasmon Resonance) 2D gas sensor elements having sub-pixel patterns adjusted by image analysis. Linear regression analysis was employed to successfully estimate the gas concentration. This sensor device is expected to be applied to gas image sensors that can visualize odor and gas distribution.
