Abstract: A chiral cell includes a cell structure. The cell structure includes an upper ring, a middle ring, a lower ring, upper connecting rods, and lower connecting rods. The upper ring and the lower ring have the same geometrical shape, and the middle ring is located between the upper ring and the lower ring. A plurality of upper connecting rods is provided; the two ends of each upper connecting rod are respectively correspondingly connected to the upper ring and the middle ring and the upper connecting rods are obliquely and uniformly distributed between the upper ring and the middle ring; a plurality of lower connecting rods is provided; the two ends of each lower connecting rod are respectively correspondingly connected to the lower ring and the middle ring and the lower connecting rods are obliquely and uniformly distributed between the lower ring and the middle ring.
