Researchers at Georgia Tech have come up with a small and flexible brain sensor that can sit just under the skin, between our hair follicles. It is designed to be comfortable enough to wear all day and does not need any wires or gel to work. These sensors are part of what’s called Brain-Computer Interface (BCI) technology.
This new sensor uses tiny microneedles to get a better reading of brain signals. In testing, it was able to tell what users were focusing on with about 96% accuracy. The idea is that this could make hands-free tech like smart glasses or prosthetic controls easier to use in everyday life.
The device worked for up to 12 hours straight, even while people moved around. Professor Hong Yeo, who led the project, said the goal was to make brain sensors better for everyday use, especially in healthcare. The sensor picks up signals from our brain and sends them to devices like smart glasses, computers, or even robotic limbs. During testing, people were able to use it to control an AR video call, all just by focusing their eyes. Since it works while we are walking, running, or doing regular tasks, it could be a big step toward using this tech in everyday life.
With the support from international collaborators and funding programs, they were able to conduct this project and made this research possible. The team hopes this could be helpful in areas like healthcare and rehabilitation in the future.
