Figure | Working principle of the omnidirectional wavelength tuning.

Caption

a) Illustration of the omnidirectional wavelength-tunable color device featuring a mechanochromic chiral liquid crystal elastomer (CLCE) and an electrically deformable dielectric elastomer actuator (DEA). b) Demonstration of reflection wavelength tuning capabilities towards both longer and shorter wavelengths. c-f) Schematic diagrams detailing the operations of the DEA in various modes: (c) contraction mode, (d) stretching mode, and (e) omnidirectional mode by integrating contraction and stretching modes; (f) depicts the helix deformation of the CLCE under each respective tuning mechanism.
