DESCRIPTION provided by applicant Traumatic brain injury TBI is an acquired neurological disorder that can cause long lasting disability with limited treatment options Therefore preventative strategies must be emphasized in high risk activities to reduce the individual and societal burden of this pervasive injury Bicycle activities account for of all
sports related TBI with annual injuries in the US In an effort to alleviate the incidence
and severity of these head injuries helmet usage is now recommended and in some states mandatory However contemporary bicycle helmets are not designed to mitigate rotational head acceleration which is a clear physical mechanism of TBI A novel helmet using High Impact Velocity Engineering HIVE technology is therefore proposed that combines recent advances in material science with an innovative suspension technique to provide superior energy absorption in a lightweight and cost effective design A key innovation of the HIVE helmet is that its structural properties behave similar to a torsional spring and damper and thus
enable the HIVE helmet to attenuate severe rotational head accelerations The STTR Phase I delivered conclusive evidence on the feasibility of HIVE technology HIVE prototype helmets yielded up to reduction in rotational head acceleration and up to reduction in predicted TBI risk compared to standard bicycle helmets The aim of this STTR Phase II research and development strategy is to formally optimize the performance of HIVE technology by combining computational modeling and physical validation The optimized HIVE technology will be translated into a commercially viable helmet design The resulting HIVE helmets will be evaluated in vertical and oblique impacts to quantify performance improvements compared to standard helmets If successful the final HIVE helmet design can readily be commercialized to offer advanced head protection for bicyclists and to reduce the incidence and severity of bicycle related TBI PUBLIC HEALTH RELEVANCE There are bicycle related traumatic brain injuries TBI that occur annually in the U S with an associated societal cost of $ billion per year Althoug bicycle helmets should offer a clear preventative strategy to reduce bicycle related TBI contemporary bicycle helmets are not engineered to attenuate rotational head acceleration a primary physical mechanism of TBI A helmet impact mitigation technology is proposed that absorbs rotational energy and therefore will potentially reduce the high incidence of bicycle related TBI
