Dissolvable brain implants to monitor swelling
Implantable devices to monitor brain injuries that don't need to be removed
The only way right now for doctors to monitor potential swelling is by surgically implanting sensors directly onto the brain, using cumbersome wires hooked directly up to a monitor. Then, once the critical period has passed, all of these things need to be surgically removed. But in the future, doctors might be able to keep tabs on the brain, using a system that would eventually just melt away.
Dr. John Rogers is a professor of Materials Science and Engineering at the University of Illinois in Urbana-Champaign, and head of a team that has developed dissolvable brain sensors.
