The object
Peter Halldin invented the sliding-layer helmet structures used by MIPS to reduce rotational motion transmitted in an oblique impact. The protective component has been incorporated into commercially manufactured sports helmets, making rotational-impact management a prominent design criterion in modern helmet safety.
What Peter did
Invented helmet sliding-facilitator structures for MIPS that let helmet layers move relative to one another during angled impacts.
Why it matters
MIPS technology is licensed across major helmet brands, while Halldin's 2024 patent publication documents continued invention of helmet sliding interfaces.
Living-status check
A MIPS helmet patent naming Halldin as inventor was published on 23 May 2024, positive dated evidence of his living technical activity in 2024.
