University of Illinois researchers have developed materials that not only heal, but regenerate - and not just tiny microscopic cracks, large cracks and holes. All by regrowing material.
The regenerating capabilities build on the team's previous work in developing vascular materials. Using specially formulated fibers that disintegrate, the researchers can create materials with networks of capillaries inspired by biological circulatory systems.
Such self-repair capabilities would be a boon not only for commercial
goods – imagine a mangled car bumper that repairs itself within minutes of an accident – but also for parts and products that are difficult to replace or repair, such as those used in aerospace applications.
