The Hydrogel's Memorizing-Forgetting Behavior

Caption

The hydrogel's memorizing-forgetting behavior is achieved based on fast water uptake (swelling) at high temperature and slow water release (shrinking) at low temperature, which is enabled by dynamic bonds in the gel. The swelling part turns from transparent to opaque when cooled, enabling memory retrieval. (Chengtao Yu et al., PNAS, July 27, 2020)
