Liquid crystal micro-particles are functional materials possessing attractive properties such as optical and dielectric anisotropies, and are fabricated by polymerizing pre-aligned molecules in the liquid crystalline state. Here we demonstrate orientation control of liquid crystal micro-particles in a dual-frequency liquid crystal host by applying electric field with different frequencies. Rectangular-shaped micro-particles with inner molecular alignment along the long axis were fabricated via two-photon excited direct laser writing, and driven by an electric field applied in the in-plane direction of the cell. Constructed theoretical model considering three-dimensional director distribution of the host around the particle provides insight into the unique behavior of the liquid crystal-liquid crystal particle composites.
