(b) Schematic diagram and real deformation of the bending state and construction of the actuator under NIR and UV lamp (Reprinted (adapted) with permission [107].

(d) Schematic diagram of a polymeric film that was constrained at both ends and reacted with an oblique-incidence light source (left). The blue arrows show the way the film deformed while the red ones indicate the propagation direction of the wave (Reprinted (adapted) with permission [96]. Copyright (2019) John Wiley and Sons).
