Blunt and blast impacts occur in civilian and military personnel, resulting in traumatic brain injuries necessitating a complete understanding of damage mechanisms and protective equipment design. However, the inability to monitor in vivo brain deformation and potential harmful cavitation events during collisions limits the investigation of injury mechanisms. To study the cavitation potential, we developed a full-scale human head phantom with features that allow a direct optical and acoustic observation at high frame rates during blunt impacts.

In this data brief, materials used to simulate brain tissue and skull are characterized for application in a full-scale human head phantom. Polyacrylamide hydrogels are implemented as tissue scaffolds and tissue mimics because they are bioinert and tunable.

- - Traumatic brain injury (TBI) is a significant health issue for both military and civilian groups, with ongoing challenges in understanding how different types of impacts lead to injuries.
- - The study introduces the ANGUS phantom, a synthetic brain model made from polyacrylamide gel, designed to simulate human brain properties and improve research on TBI without using animal models.
- - Mechanical comparisons between the ANGUS phantom and human subjects show that while the phantom accurately mimics responses to certain types of impacts, it falls short in modeling responses to rotational impacts, highlighting areas for further research.
