Ten NFL teams already had been using these sensors for the last few years.
Officials at the respective schools said about 35 players were using the mouthguard sensors at Washington and 20 at Alabama.
Daniel Cobian, a professor of orthopedics and rehabilitation for Wisconsin’s school of medicine and public health, said the sensors went to linemen and tight ends.
“We’ve noticed players are pretty hard on their mouthguards,” said Kimberly Harmon, a professor of family medicine and orthopedics and sports medicine at Washington’s school of medicine.
The sensors collect kinematic data, including impact speed, direction, force, location and severity.
Sills noted that a previous study had engineers looking at every concussion that took place in NFL action over a period of several years.
