Abstract
An environmental condition sensing device includes an interferometric modulator with optical properties, which change in response to being exposed to a predetermined environmental threshold or condition. The device includes an environmental reactive layer, which alters composition, in an optically-detectable manner, in response to being exposed to a predetermined environmental threshold or condition.
Claims20
An environmental condition monitoring device, comprising:
- an interferometric modulator (IMOD) comprising:
- a substrate;
- an optical enhancement layer disposed on the substrate, the optical enhancement layer comprising a reflector layer;
- and
- an environmental reactive layer disposed on the optical enhancement layer, the environmental reactive layer having a composition capable of being altered in response to exposure to an environmental condition.

An environmental condition monitoring device, comprising:
- means for modulating light, comprising:
- a substrate;
- an optical enhancement means disposed on the substrate, the optical enhancement means comprising a light reflecting means;
- and
- an absorbing means for altering the reflectivity spectrum of the light reflecting means in response to exposure to an environmental condition, wherein the absorbing means is disposed on the optical enhancement means.
