STRUCTURAL COLORIMETRIC SENSOR

摘要

A colorimetric sensor including: a substrate; and a periodic array of nanostructures provided to the substrate, wherein the periodic array of nanostructures is configured to provide a change in color based on a medium being within a predetermined distance of the colorimetric sensor. The periodic array of nanostructures may be configured (width, height, spacing) to provide optical wave-guide properties or surface Plasmon resonance in order to effect a distinct change in color based on the medium being sensed. In some cases, the colorimetric may include a reflective surface to reflect light from the sensor. Further, the reflective surface may be metallic.
