Microgel-Crosslinked Thermo-Responsive Hydrogel Actuators with High Mechanical Properties and Rapid Response

Front Cover: In article 2300643, Rong Wang and co-workers develop a facile way of constructing thermo-responsive hydrogel actuators based on a poly(N-isopropylacrylamide) microgel cross-linking strategy. The bilayer hydrogels show enhanced mechanical properties and tunable response rates, making them highly promising for applications of smart actuating devices.
