Self-healing

The soft, self-healing exterior of this robot will allow it to take damage, retreat, and then return to combat.

They’ve actually created a synthetic gel that mimics the mussel’s sticky, self-healing properties.

Self-healing plastic could be used in a number of ways, White said. For example, it could be used as a protective coating on metal.

Indigenous bacteria, which naturally exist in specific environments, are being increasingly utilized in self-healing cement to promote calcite precipitation, a process that fills cracks and restores the material’s structural integrity [4,5].

This study also explores the role of environmental conditions, such as wet and wet–dry cycles, in optimizing the self-healing process, revealing that cyclic exposure conditions further improve the efficiency of strength recovery.
