Four bioinspired structures. (a) The spider web: (a1) the transverse shape of the honeycomb structure; (a2) the transverse shape of the negative Poisson structure. (b) Honeycomb structure. (c) Arc-honeycomb structure. (d) Negative Poisson structure. (e) Arc negative Poisson structure. R is the radius of the honeycomb structure. r is the radius of the negative Poisson structure.
