Abstract
Smart (stimuli-responsive) hydrogels constitute a material class suitable for transducers in sensing applications due to their volume-phase transition in response to a change in environmental parameters. In order to assess the viability of new hydrogel compositions for sensing, an easily applicable yet reliable characterization method for relevant static and dynamic properties of the gels, such as swelling and deswelling time constants, repeatability, stability as well as the relative swelling ratio, is crucial. Here we present such an easy-to-implement and affordable method based on the optical detection of the hydrogel's swelling state. We demonstrate the method's viability for characterization of various samples and discuss its advantages and limitations. Additionally, we fully describe the necessary experimental setup, software for automated data evaluation and corresponding procedures to allow interested researchers to implement the method in their own laboratories.
