Brain Computer Interfaces, or BCIs are futuristic devices that do exactly what it says on the tin; Allow a brain to interface directly with a computer. While this may sound like pure science fiction, it's actually even better, it's science fact. BCIs are being used all the time to help aid people in all sorts of ways. One BCI might be used to help a paralyzed user navigate their phone and talk to loved ones by monitoring brave waves, another may help an amputee use their prosthetic limb, while others might just monitor brain waves for research purposes. Now one team at Georgia Tech has managed to further the use of BCIs by developing new tiny interfaces that can be inserted between hair follicles.
While BCIs are already well and truly out there and established, they could still be better. One of the biggest hurdles BCIs face is finding the balance between being a robust piece of tech that can effectively monitor and translate brain signals, with being something fairly inobtrusive a user can wear.
