Vibrating Sensors Detect Concussions

Nov-25-17 A tiny, vibrating sensor able to detect protein in blood could offer an early screening tool for disease and injury.

Developed by a team from Purdue University, the sensors are outfitted with a “piezoelectrically actuated resonant microsystem,” which is able to detect changes in mass. Presently, the device is able to detect minute amounts of protein in a blood sample, including the protein from glial cells that is released after a brain injury.

According to the team, the sensor could be used to screen athletes in mass for signs of brain injuries, and could also be adapted to detect other diseases marked by protein secretion.
