The case study we are looking at is an exciting British company called D3O – also the name of its patented smart material. D3O (the material) is a next-generation shock absorber offering impact protection solutions to an ever-growing range of markets. The clever science bit is that its molecules go from a normal soft and flexible state, to locking together upon shock, before returning to their flexible state. In simpler terms it goes from gooey, too hard, and back to gooey when it endures impact. And the harder the impact the harder the material becomes. Clever stuff and here is a video to show just how remarkable it is.
