“…Remarkably, LCE is capable of sensing external stimuli, making judgments, and exhibiting reversible, large, and complex shape changes in response to different stimuli. The above conventional stimuli include thermal, 21,22 electric, [23][24][25] humidity, 26 and magnetic. 27 The light control is particularly attractive, because of its non-contact remote capability, rapidity, and precision.…”

Liquid crystal elastomers (LCEs) have wide and potential applications in artificial muscles, soft robots, biomedical devices, and so on. On the application of LCE plate in text display, different from others' work where specially shaped ultraviolet (UV) lighting is used, in this paper, the programmable deformation of LCE plates with arbitrary liquid crystal orientation subjected to uniform light illumination is investigated. A photomechanical coupling finite element method (FEM) is developed, in which the impact of the shear strains induced by light is taken into account. Inspired by the FEM, the LCE plate is divided into finite small regions. By altering the liquid crystal orientation of each region in the LCE plate, the ability to generate 24 letters and 10 numbers through light‐induced deformations is demonstrated. Matrixes of the liquid crystal orientation corresponding to each letter and number are provided. This work indicates that it is possible for blind people to read text information by touching the deformed LCE plate.

“…Based on these data, the temperature distribution of metal substrate alloys with different thickness is predicted by ANN. Wang et al (2022) used the exact 2-D thermoelastic model of laminated beam to establish a BP neural network database containing 561 sets of data for predicting the mechanical solutions of laminated beam. It would be of significance to apply the BP neural network to predict the mechanical properties of 3-D laminated plates under combined thermo-mechanical loads.…”
