This small sensor could make huge impacts on brain injury treatment

Monitoring pressure inside the skull is key to treating traumatic brain injuries and preventing long-lasting complications, but most of the monitoring devices are large and invasive. Now, researchers from Georgia Tech and Louisiana State University, along with international collaborators, have created a nanosensor made from ultra-thin, flexible silicone that can be embedded in a catheter. Once the catheter is in a patient’s skull, the nanosensor can continuously gather data at a more sensitive rate than traditional devices. With this nanosensor, even the smallest pressure changes could alert clinicians that further treatment is needed.
