When one tiny circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss.
Researchers have found a way to pump self-healing fluids around a material similar to an animal's blood circulation.
Parachute cords, climbing ropes, and smart coatings for bridges that change color when overstressed are several possible uses for force-sensitive polymers being developed by researchers at the University of Illinois.
U.S. scientists say they are developing polymers that, when overstressed, change color -- making them ideal for applications such as bridge coatings. The force-sensitive polymers being developed at the University of Illinois contain mechanically active molecules called mechanophores.
