Prototype development of a silicone tissue model for AHT test systems

In Western countries, an estimated 20 to 40 out of every 100,000 infants suffer abusive head trauma (AHT), although the actual number of cases is likely to be significantly higher due to a high number of unreported cases. This type of brain injury is caused by negligent or intentional abuse. Up to 96% of surviving children suffer long-term neurological damage, and the mortality rate is as high as 36%. Typical findings include subdural hematomas and diffuse brain damage. The aim is to develop a brain model that simulates the stresses that occur in AHT and enables a targeted correlation between the force applied and the injury pattern.

Task:

The aim of this work is to develop a silicone-based substitute material for replicating infant brain tissue. To this end, commercial silicones with suitable Shore hardness are first selected and their property profile is enhanced by the defined addition of silicone oil. After analyzing the mechanical properties, test specimens are produced from the mixtures and evaluated in an expert study with regard to haptics and tissue similarity.

The results of this work will make an important contribution to improving the data available in AHT research and support the development of an anthropomorphic test system. This will lay the foundation for further scientific research and a more informed assessment of childhood injury patterns.

Profile:

• Master's student in mechanical engineering, materials science, medical technology, or a similar field of study
• Interest in biomechanical issues, medical technology, and product development
• Analytical thinking skills and enjoyment of scientific work
• Independent and structured approach to work
