Mechanical characterization and self-healing in synthetic vascularized materials
… self-healing materials have been developed that mechanically recover from structural damage autonomously. One strategy for creating self-healing materials is to distribute reactive fluids throughout the material volume using a microvascular network of microchannels that serve as conduits of flow …
