SMART BRAIN

Smart Brain

A biomimetic model of the human skull and brain to understand how concussion and TBI affect brain structure and function.

According to the Brain Injury Association, one in 60 adults is living with some form of disability related to traumatic brain injury (TBI). To develop more effective interventions for workers and athletes against concussions and TBI, such as helmets, in-depth knowledge is required of how brain matter moves within the skull and how these injuries affect brain structure and function.

The Smart Brain is a highly advanced research tool for understanding the link between impact and injury. It is the result of a novel synthesis of fluid mechanics, materials, instrumentation and manufacturing processes. The 3D-printed hydrogel brain sits within a transparent skull and mimics the geometry and mechanical properties of the human brain to provide insights into injury mechanics by: (1) determining how and why a brain injury occurred, (2) measuring cerebrospinal fluid pressurization and (3) recording acceleration and surface deformation data resulting from the impact.
