Future Helmet Creates a Stink When You Crash

A team of researchers at the Fraunhofer Institute for Mechanics of Materials IWM in Freiburg has been testing out a new manufacturing process that injects microcapsules filled with a odor-causing oil into the materials that go into a helmet. When the protective layer is cracked, you’ll be able to big up a smell coming from your helmet. It’s proportional, so a big crack will let off quite the stink.

“Cyclists often replace their helmets unnecessarily after dropping them on the ground, because they cannot tell whether they are damaged or not,” Dr. Christof Koplin, a research scientist at the IWM, said. “The capsules eliminate this problem. If cracks form, smelly substances are released.”
