A team at a university built a protective device called the MIPM. It is flexible at rest and can curl into a round shell when touched or hit.
The device is inspired by armadillos and can protect fragile technologies such as soft robots and flexible electronics. A sensor in the device senses strain and then a heating layer makes parts move so the outer shell curves and closes around the object.
Early tests showed the sensor triggered the change and more rigid segments made the shell stronger.
