Fast Optical Humidity Sensor Based on Hydrogel Thin Film Expansion for Harsh Environment
With the application of a recently developed deposition method called initiated chemical vapor deposition (iCVD), responsive hydrogel thin films in the order of a few hundred nanometers were created. When in contact with humid air, the hydrogel layer increases its thickness considerably. The measure...
