Fast industrial hydrogel sensors require thin polymer films with reproducible properties as sensing layer. The manufacturing process of such hydrogel coatings in the submicrometer range has been investigated with respect to a sufficient and reproducible sensitivity in order to create the necessary knowledge for a quality-assuring volume production. Interrelations between process parameters, the resulting hydrogel coating properties and the sensor behavior have been studied by means of batch manufacturing tests and direct measurements of film parameters. Furthermore, the manufacturing process of a sensor solution for surface technology with PVA/PAA hydrogel as sensing layer has been successfully optimized. The presented basic coating process and methods for its application-specific optimization are applicable for various industrial sensor designs with different hydrogels.
