Kirigami Metastructures: Liquid-Crystal-Elastomer-Actuated Reconfigurable Microscale Kirigami Metastructures (Adv. Mater. 25/2021)

Achieving wireless miniaturized reconfigurable metastructures remains a challenge due to the difficult nature of the fabrication and actuation processes at the micrometer scale. In article number 2008605 , Metin Sitti and co-workers develop an actuation platform for thermally reconfiguring micro-metasurfaces by using uniaxially aligned liquid crystal elastomers, which serve as efficient artificial muscles to provide energy for actuation of the microscale kirigami metastructures.
