Helmets are far from the brain buckets (basically shells) of times past.
Advancements in the use of foam and other insulations have come a long way in better protecting the brain, but it remains a challenge to engineer against high velocity impacts coming from different angles. It takes more than just adding padding; in fact, more padding can cause more damage as the material packs out over time, creating more space between the shell and head.
Enter MIPS, which stands for Multi-directional Impact Protection Systems. MIPS started in Stockholm, Sweden by five biomechanical specialists at the Royal Institute of Technology (KTH) in 2001 to create the most cutting-edge brain protection system. With the help of neurosurgeon Hans Von Holst, who was fed up with patients still getting traumatic brain injuries despite wearing helmets, and researcher Peter Halldin, the MIPS technology was developed into a helmet that supports energy dispersion and absorption, rather than just buffering against direct impact.
