We have developed a set of materials with mechanical performance similar to the mechanical properties of cartilage tissue. The materials contain water as their majority component and assemble from a combination of appropriately designed polymers and soluble metal ions such as calcium and zinc. Because the materials do not rely on the formation of irreversible covalent bonds for their strength, they have a “self-healing” character that allows them to be repetitively deformed many times, even after partial failure of the material has occurred.
