A group of researchers from Stanford University has developed a football helmet that features liquid shock absorbers. This innovative design may significantly reduce the impact of concussions in the sport. The helmet, which was developed at Stanford’s Camarillo Lab, consists of 21 liquid shock absorbers that outperformed existing gear during a virtual model simulation. The results, published in the journal Frontiers in Bioengineering and Biotechnology, showed that the new helmet reduced the effects of impact by 33% when measured using the Head Accelerate Response Metric (HARM score), a technique for evaluating helmet performance under impact. The research also tested lower-impact hits, finding that the helmet’s liquid technology offered an average improvement of over 30% for both low and high velocities. The study is personal for most of the research team, who have personal connections to traumatic brain injuries and care deeply about athlete brain health. The helmet’s face mask and chinstrap still require refinement, but researchers hope to conduct human studies in the future to demonstrate a reduction in concussion incidence or an attenuation of impact severity for sub-concussive impacts.
