Abstract:
1. A method comprising: providing a first layer comprising a first surface; providing a second layer comprising a second surface, wherein the second surface is physically adapted to move in response to an environmental stimulus; securing the first layer and second layer together via an adhesive mixture, wherein the adhesive mixture comprises an adhesive and a plurality of spacers, and wherein each of the plurality of spacers is characterized by a dimension that is substantially equal to a first thickness, and further wherein the secured first surface and second surface collectively define an optically resonant cavity having an initial cavity length substantially equal to the first thickness; distributing light received by the optically resonant cavity into a reflected signal and a transmitted signal, wherein the light is characterized by a first wavelength, and wherein the ratio of light in the reflected signal and transmitted signal is based on the environmental stimulus; and producing a first electrical signal based on both (1) the intensity of the reflected signal and (2) the transmitted signal.
