Could our future cities heal themselves just like human skin?
In short: Engineer Mark Miodownik introduces a revolutionary class of materials called animate matter. These substances are designed to sense structural damage, repair themselves automatically, and biodegrade once their lifecycle ends, potentially transforming how we build our infrastructure.
In a talk recorded at TED2025 on April 10, 2025, Miodownik argues that the next significant advancement for humanity is not simply producing more goods, but creating materials that resist decay and failure. By mimicking biological processes like skin regeneration, these self-healing materials could extend the lifespan of roads, bridges, and urban environments.
This shift toward animate matter represents a fundamental change in engineering philosophy, moving away from static structures toward systems that actively maintain their integrity.
