Inspired by biological systems that can self-repair, Diane Gardner is working on polymer 'ligaments', micro capsules of regenerative fluid and even embedded bacteria that can help concrete to repair itself when it cracks. The technology has the potential to dramatically increase the lifespan of concrete instillations, reducing their carbon footprint and maintenance costs.
