This patch measures pressure on the neck from sudden impacts. It may better detect brain injuries.
Hits to the head are common in football. These hits can cause concussions, brain injuries that need quick treatment. Many helmets have sensors to detect dangerous hits, but the devices can be heavy and inaccurate. That’s why Michigan engineers designed an improved device.
The small patch is worn on the neck. When it’s stretched or squeezed, sensors send an electric signal to a computer. During games, medics would be able to monitor brain movement in real time. That could help athletes get immediate care.
Engineers tested the patch on a dummy by simulating strains to the neck. The patch detected concussion-causing movements better than other devices. Soon they will test it on humans.
