Researchers at Germany’s Fraunhofer Institute have created bicycle helmet that stinks when damaged.
Helmet manufacturers state that once the helmet becomes cracked, the integrity of the helmet safety structure is compromised and becomes less effective.
Fraunhofer have come up with a process that injects microcapsules of malodorous oils into the helmet itself, causing it to smell when damaged, thus alerting the user that it’s time to replace it.
