Auxetic web structure or field structure, and use

An auxetic web structure or field structure comprising:

• island structure areas and
• interconnections between the individual island structure areas,
• wherein
• there are open spaces between the individual island structure areas, and
• the connections with the island structure areas form a web structure or field structure;
• wherein
• the connections are extensible and are configured as Archimedean spiral connections and/or self-similar fractal design connections;
• the connections intersect the island structure areas at the same location and at the same angle intersect the auxetic framework at the same location and angle as the previous rigid connectors;
• the island structure areas are not bendable or are only slightly bendable when subjected to forces,
• wherein the stresses on the island structure areas are at least one order of magnitude below those of the extensible connection
• and/or
• are not or only insignificantly variable in their magnitude
• and
• the Poisson's ratio of the structure under uniaxial deformation is negative.
