Pressure sensors for printed blast dosimeters

Disposable printed sensor tapes are being developed to record the magnitude of explosive blasts in the battlefield. The goal is to detect and mitigate the possible occurrence of traumatic brain injury in soldiers. This paper presents results on the pressure sensors to measure the blast pressure and the blast noise. The sensors are based on piezoelectric polymers and their fabrication is compatible with roll-to-roll fabrication methods to enable low cost.
