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.

Abstract: A silver paste ink composition comprises a plurality of first particles comprising silver; a polymer binder; a carrier solvent; and a plurality of second particles comprising silver. The second particles are nanoparticles that are different than the first silver particles, the amount of second particles in the ink composition being sufficient to impart a first color to the uncured ink composition, the first color being different than the color of the same ink composition without the nanoparticles. The silver nanoparticles have a property of causing a change in the color of the ink composition when the ink composition is cured.
