p A new device could let paralyzed people control exoskeletons with their thoughts.
Developed by researchers at the University of Melbourne, the device plugs directly into the brain without doctors having to perform surgery on the skull.
Stents are used by cardiologists to prop open blood vessels, and this implant is designed around one; it slides through an incision made in the jugular vein up to a blood vessel near the motor cortex in the brain.
At the end of the stent, a metallic mesh with electrodes picks up brain activity and relays this information to a recording device in the wearer’s chest, which wirelessly transmits it to an external computer that will control the exoskeleton.
The researchers have called their device a “stentrode.”
When a wearer thinks about a certain direction — for example, left — the brain fires in a particular way.
