From: Omnidirectional color wavelength tuning of stretchable chiral liquid crystal elastomers
a Schematic representation of the vertical structure of the omnidirectional-mode CLCE. b Top view of the omnidirectional-mode CLCE before voltage application. c, d Reflection wavelength shift toward (c) shorter wavelengths using the stretching mode and (d) longer wavelengths using the contraction mode. e, f Central wavelength (e) and central wavelength shift (f) as a function of the applied voltage. g Omnidirectional structural color changes at various applied voltages
