Implantable Sensor for Monitoring Brain Injury
“In the event of a traumatic brain injury (TBI), chemical changes take place that can act as precursors for secondary damage, and scientists at Ohio State University have demonstrated a new monitoring device that can pick up these warning signs. The team’s tiny sensor is flexible and thinner than a human hair and could be worn on the brain to relay these changes in real-time, potentially offering new avenues for intervention and treatment. The waterproof biosensor consists of a set of field-effect transistors that, when they sense certain chemicals in brain fluids, produce an electrical signal that can be picked up and analyzed from outside the body. To protect the electronics from degrading, the sensor is housed inside a thin film of silicon dioxide a few hundred nanometers thick.” MORE
