New Sensor System Detects Early Signs of Concussion in Real Time

A wireless health-monitoring system, developed by researchers at the University of Arkansas, detects early signs of traumatic brain injury in athletes by continuously monitoring various brain and neural functions. The technology makes it possible for a physician to continuously monitor each player’s physiological signs that indicate concussion. The system is a network of flexible sensors woven or printed into a skullcap worn under a helmet. The sensors are built with carbon nanotubes and two- and three-dimensional, textile nanostructures. The system includes a pressure-sensitive textile sensor embedded underneath the helmet’s outer shell, which measures intensity, direction and location of impact force, while the other sensors work as an integrated network within the skullcap. The system then uses wireless telemetry to transmit data from the sensors to a receiver, which then transmits the data via a wireless network to a remote server or monitor, such as a computer. “In real time, our system continuously monitors neural activity and recognizes the signs and symptoms of traumatic brain injury, such as drowsiness, dizziness, fatigue, sensitivity to light and anxiety,” said Vijay Varadan, distinguished professor of electrical engineering.
