This nearly invisible brain-computer
interface lets you control devices with your mind required. no wires
Georgia Tech researchers have unveiled a breakthrough brain-computer interface (BCI) that is nearly invisible, entirely wireless, and designed for real-world mobility.
The device, smaller than a millimeter, slips between hair follicles and sits just beneath the skin using microneedles that painlessly reach the scalp’s surface.
Unlike traditional BCIs that require bulky headgear or conductive gel, this tiny sensor captures brain signals with 96.4% accuracy even while the user walks or runs.
In testing, participants controlled augmented reality video calls using only their brain activity, selecting contacts by focusing on visual prompts.
The device remained effective for up to 12 hours of continuous use. This advancement could be life-changing for people with disabilities or neurological disorders, offering a noninvasive way to interact with technology and the world. For the wider public, it opens up new possibilities for hands-free control in AR, VR, and smart environments bold step toward seamless human-machine integration.
