Abstract

A display or sensor device includes a nano-stepped or nano-dimpled solid surface. The device produces a color readout in response to an optical interference effect between light reflected from a bottom and a top of a step or a dimple of the surface. The device is adapted to detect a change in the reflected light in response to a presence of a fluid and/or a change in a property of the fluid. A fluid source is adapted to deliver or remove a transmissive fluid to or from the step or dimple, which causes a change in the color readout or reflectance spectrum.
