Hard or soft? State-shifting new material can be both
Researchers at Waterloo Engineering have created a new material that can go from a soft gel to a hard solid and back again at the same temperature.
The switchability of the material - a combination of supercooled melted salt and polymers that the researchers call sal-gel - means it has two stable and reversible solid states for potential use in a range of technologies including soft robotics, adhesion and adhesives, and aeronautics.

The company was one of nine out of 1,200 applicants to be chosen for the program that began July 15.
