An Air-Filled Bicycle Helmet for Mitigating Traumatic Brain Injury

We created a novel air-filled bicycle helmet. The aims of this study were (i) to assess the head injury mitigation performance proposed helmet and (ii) compare those results against an expanded polystyrene (EPS) traditional Two types subjected impacts in guided vertical drop tests onto flat anvil: EPS helmets (Bumpair). maximum acceleration value recorded during test on Bumpair was 86.76 ± 3.06 g, while first shock reached 207.85 5.55 g (p < 0.001). For helmets, increased steadily over number shocks. There strong correlation between response (cor = 0.94; p 0.001), showed less significant dependence time 0.36; 0.048), meaning previous had lower consequence. significantly reduced maximal linear when compared helmet, showing improvements impact energy mitigation, as well resistance repeated impacts. This concept could improve cyclists.
