From the cellular level up to the body system level, living organisms are able to sense and adapt to local environment for various functions, from detecting and transporting molecules in the complex bio-fluids to harvesting energy from the environment and generate motions to keep alive. These graceful capabilities arise from the coordination of the chemo-mechanical actions, such as the molecular configuration changes and micro/macroscopic mechanical motions. Stimuli-responsive hydrogels are a class of synthetic materials that can change their volume and physical properties in response to environmental cues including temperature, light, and specific molecules.
