Biography

Dr Rémy Willinger serves as a  professor at the ICube laboratory is heading a research team in biomechanics. He particularly focuses on the head-neck system. Under his leadership, the team developed a digital model of the human head capable of calculating bone deformations of the cranium, quantifying the relative brain-skull movement and apprehending the elongation of axon bundles - the extensions neurons that transmit nerve impulses - in the event of any shock.

  A principal cause of traumatic brain injury is rotational head acceleration, which can induce brain injury even in absence of a direct impact to the head. A bicycle fall typically leads to an oblique impact of the head that induces rotational head acceleration. To mitigate this rotational head acceleration, a novel bicycle helmet concept has been developed that employs a collapsible cellular structure. This study quantified the efficacy of this technology in comparison to traditional bicycle helmets made of rigid Expanded Polystyrene (EPS). Prototype helmets  with the Cellular structure (CELL) and standard EPS helmets (CONTROL) were subjected to oblique impacts in vertical drop tests onto angled anvils. Helmets were tested at impact speeds of 4.8 m/s and 6.2 m/s and at impact angles of 30°, 45°, and 60°. Linear and rotational headform acceleration and neck loads of an.. View more»
