Sensors that can be easily and safely introduced in the brain could have important medical applications and could also contribute to the development of brain-interfacing devices. While significant progress has been made toward the development of these sensors, most existing devices can only be deployed via invasive surgical procedures that can have numerous complications.

Researchers at Seoul National University and other institutes in South Korea recently created a new biodegradable and self-deployable tent electrode that could be far easier to insert onto the surface of the human brain. Their proposed electrode design, outlined in Nature Electronics, could naturally degrade inside the human body without leaving any residues, which means that once it is inserted in the body it does not...
