| Schematic representation of the omnidirectional color wavelength-tunable device.
a Schematic representation of the omnidirectional color wavelength-tunable device, consisting of a mechanochromic CLCE and electrically deformable DEA. b Reflection wavelength tuning toward longer and shorter -wavelengths. c-f) Schematic representations showing operations of the DEA in (c) contraction mode, (d) stretching mode, and (e) omnidirectional mode by combining the contraction and stretching modes; (f) helix deformation of the CLCE under each tuning method.
