Hydrogel Sensors and Actuators

Hydrogels are a fascinating class of polymers which show a immense ability of swelling under the influence of temperature, the pH value or concentrations of different species in aqueous solutions. The volume change can amount up to several hundred percent. This unique behaviour is already used in such applications like disposable diapers, contact lenses or drug-delivery systems. The ability to perform mechanical work shifted the technical interest to sensors and actuators exploiting the thermo- chemo-mechano-electrical coupling. The accuracy requirements for these devices are much more demanding. Therefore, a deep knowledge of the both the material and the functional properties of hydrogel sensors and actuators is needed. The monograph describes the state-of-the-art and recent developments of this technology.
