Evaluation of Impact Loading Rates Dependency on Prescale Pressure Film

Migraine is the third most common medical condition in the world. Xiaogai Li have a hypothesis that implies that a hit to the head when first sensing the aura symptoms will stop the migraine attack. An investigation was made to ensure that the blow does not cause a head injury. The prescale pressure film from Fujifilm is a sensor that measures pressure and the pressure distribution. It is supplied with charts to determine the pressure when purchased. The pressure film was used to measure the reached loading impact from the blow. The new chart for the pressure film would in that case be used to create simulations to study the potential brain damage a hit to the head can result in. This paper examines whether loading rates has an influence on a prescale pressure film from Fujifilm, in order to create new pressure charts if such dependency is found. The testing was made with the help of a loading machine where the desired force could be set. The results showed a lower color density in the test results when comparing with the provided charts. The reason for this is unknown, although it could be a consequence of the environmental conditions that the pressure film was held in. The conclusion made by studying the results was that no loading rate dependency exists
