Smart gel is a functional material that actively changes its volume and properties (hydrophilicity/hydrophobicity) in response to changes in external environments such as temperature, pH, light, and electric fields. They have been suggested for applications such as temperature-responsive recovery of moisture from the air as water, drug delivery systems, and medical biocompatible patches.
