Title: AN ETALON OR INTERFEROMETER BASED SENSOR ASSEMBLY
Abstract:
An etalon or interferometer based sensor assembly is provided that includes a monolithic polymeric gel layer. A metal-containing overlayer is formed over a top surface of the polymeric gel layer. A metal-containing base layer supports a bottom surface of the polymeric gel layer. The base layer in turn supported by a substrate. An enclosure about a perimeter of the aforementioned components of the sensor assembly functions to limit diffusion to through the overlayer. The gel layer having a thickness that induces a color change in the sensor as the thickness changes. A process of preparing such a etalon or interferometer based sensor assembly is also provided.
