3D shape reconfiguration of stretchable electronics

Azobenzene functionalized liquid crystalline polymers are considered "smart" materials owing to their programmable shape transformations under various external stimuli (i.e., thermal, chemical, and photomechanical shape morphing). In particular, their light responsivity allows for untethered powering and actuating systems. Now, researchers from Inha University have demonstrated preparation and actuation of reduced graphene oxide patterned azo-LCN (azo-LCN/rGO) with highly enhanced elastic modulus, electrical conductivity, and photomechanical actuation performance.
