Abstract
A sensor has a transparent polymer aerogel, and sensing materials dispersed into the transparent, polymer aerogel, where the sensing materials change color in response to environmental conditions. A method of forming a sensor includes providing a substrate, forming a polymer aerogel layer on the substrate, and infusing the polymer aerogel layer with sensing molecules.
