'''Smart gel''' is a type of smart material.
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.<ref>{{Cite journal |last=Matsumoto |first=Akira |last2=Tanaka |first2=Miyako |last3=Matsumoto |first3=Hiroko |last4=Ochi |first4=Kozue |last5=Moro-oka |first5=Yuki |last6=Kuwata |first6=Hirohito |last7=Yamada |first7=Hironori |last8=Shirakawa |first8=Ibuki |last9=Miyazawa |first9=Taiki |last10=Ishii |first10=Hitoshi |last11=Kataoka |first11=Kazunori |last12=Ogawa |first12=Yoshihiro |last13=Miyahara |first13=Yuji |last14=Suganami |first14=Takayoshi |date=2017-11-03 |title=Synthetic "smart gel" provides glucose-responsive insulin delivery in diabetic mice |url=https://www.science.org/doi/10.1126/sciadv.aaq0723 |journal=Science Advances |language=en |volume=3 |issue=11 |doi=10.1126/sciadv.aaq0723 |issn=2375-2548 |pmc=5706739 |pmid=29202033}}</ref><ref>{{Cite journal |last=Zhao |first=Mingwei |last2=Yan |first2=Xiaowei |last3=Wang |first3=Xiangyu |last4=Yan |first4=Ruoqin |last5=Dai |first5=Caili |date=June 2023 |title=The development of a smart gel for CO2 mobility control in heterogeneity reservoir |journal=Fuel |volume=342 |article-number=127844 |doi=10.1016/j.fuel.2023.127844 |issn=0016-2361}}</ref><ref>{{Cite journal |last=Grove |first=Tijana Z. |last2=Osuji |first2=Chinedum O. |last3=Forster |first3=Jason D. |last4=Dufresne |first4=Eric R. |last5=Regan |first5=Lynne |date=2010-10-13 |title=Stimuli-responsive smart gels realized via modular protein design |url=https://pmc.ncbi.nlm.nih.gov/articles/PMC3282109/ |journal=Journal of the American Chemical Society |volume=132 |issue=40 |pages=14024–14026 |doi=10.1021/ja106619w |issn=1520-5126 |pmc=3282109 |pmid=20860358}}</ref>
