Outline of Final Research Achievements

To develop the liquid crystalline materials optimal for the liquid crystalline actuators, we have investigated the effect of fluid dynamics properties of liquid crystalline materials, such as viscosity coefficients, elasticity coefficients, and dielectric anisotropies, on the driving performance of the liquid crystalline actuators. From the numerical simulations on the liquid crystalline actuators, the relation between the material properties and the driving performance of the liquid crystalline actuators is explored, and the optimal values for the material properties are proposed. The liquid crystalline actuators with five different liquid crystals are experimentally tested, and the experimental results agree with the simulation results.
