The invention discloses a diamond cell plate lattice metamaterial based on sea urchin bionic inspiration and an additive manufacturing method thereof. The bone plates are divided into two groups by taking relative positions of face centers of crystal lattices and internal atoms as geometric constraints, the group A is an equilateral triangular plate, and the group B is an integrated composite plate formed by tightly splicing three full-length equal waist-sharing triangular plates according to the waist-sharing edges; and filling A and B into a unit cell frame according to a diamond lattice atomic layout to obtain a complete bone plate structure. And the spurs are arranged along the waistline direction of the group B of triangles and a path pointing to the vertexes of the crystal lattices, and form a continuously coupled support network with the bone lamella. And taking the bone lamella-bone spur collaborative unit as a prototype, sequentially performing mirror symmetry copying around three orthogonal reference surfaces, constructing a three-dimensional periodic array and obtaining a metamaterial structure. Through parameterization cooperation of the cell size, the cell wall thickness and the aperture, the relative density and anisotropy can be continuously regulated and controlled, and the composite material is suitable for application such as lightweight bearing, energy absorption and vibration reduction isolation.

Surface polarity of a ferroelectric nematic can be configured to generate vectorial control of the orientation of its bulk polarization field. The contact between a surface with in-plane polarity and a ferroelectric nematic liquid crystal generates preferred in-plane orientation of the ferroelectric polarization field at that interface, which can lead to the formation of fluid or glassy monodomains of high polarization without electric field poling. Materials surfaces can be used as a route to making planar-aligned cells with a variety of azimuthal director / polarization structures, including twisted states, in a π-twist cell, obtained with antiparallel, unidirectional buffing on opposing surfaces, we demonstrate three distinct modes of ferroelectric nematic electro-optic response: intrinsic viscosity-limited field induced molecular reorientation, field-induced motion of domain walls separating twisted states of opposite chirality; and propagation of polarization reorientation solitons from the cell plates to the cell center upon field reversal.
