Ani Surabhi’s Biomimetic ‘Kranium’ Corrugated Bicycle Helmet Is Stronger, Lighter Than Traditional EPS


We first saw Anirudha Surabhi ‘s “Kranium” bicycle helmet shortly after he presented his graduation project at the Royal College of Art. Two years and £20,000 (courtesy of a James Dyson grant) later, the “Kranium” will finally be available to savvy cyclists in Europe. Surabhi, who goes by Ani for short, essentially designed the helmet from scratch: “the revolutionary Kranium liner is based on the corrugated structure found in the woodpecker and it is this structure, which provides the right amount of crumple zone to absorb impact energy.” Expanded polystyrene (EPS) helmets are proven to protect your head only 20% of the time. The Kranium liner has proven to absorb 3 times the amount of impact energy during collision. At the same time, it is 15% lighter than Polystyrene helmets. EPS helmets are made from petroleum based products where are the Kranium liner is made from recycled paper. They have been tested at several test labs across the globe, including TUV in Germany and HPE in the UK. They have been developed for mass production and will be available in the market in December 2012. As Ani explains in the must-see video (below), the project originated in his final year at the Royal College of Art, when he had the misfortune of falling off his bike and cracking the helmet which he was wearing at the time. The rest, as they say, is history: Having suffered minor concussions, I decided to take this as a design challenge and create the safest helmet on the planet. Looking into nature, the woodpecker is one of the only animal which experiences the same kind of impact on a regular basis. In fact, it strikes the tree ten times a second and closes its eyes every time so that they don’t pop out, which means a monumental amount of energy that goes through its head. (more…)
