Copper Film Enables Accurate Optical Humidity Sensing

Abstract:
The sensor material could be applied onto the package itself, according to Norman A. Lüchinger from the Institute for Chemical and Bioengineering at ETH. It is based on carbon-coated copper nanoparticles suspended in a polymer matrix to create a stable water dispersion. During preparation of copper dispersions, the researchers found, almost by accident, that they showed strong and vivid coloration patterns when in contact with humid air.
