New nanoscale brain sensor exhibits 96.4% accuracy in identifying neural signals
The new minuscule brain sensor, developed by Georgia Tech, uses microneedles to stay attached to the wearer, eliminating the need for conductive gel.
Researchers from Georgia Institute of Technology (Georgia Tech) have developed a microscopic brain sensor which is so tiny that it can be placed in the small gap between your hair follicles on the scalp, slightly under the skin. The sensor is discreet enough not to be noticed and minuscule enough to be worn comfortably all day.
Brain sensors offer high-fidelity signals, allowing your brain to communicate directly with devices like computers, augmented reality (AR) glasses, or robotic limbs. This is part of what’s known as a Brain-Computer Interface (BCI).
To date, brain signals are typically captured non-invasively with electrodes mounted on the surface of the human scalp using conductive electrode gel for optimum impedance and data quality. However, these electrodes are generally uncomfortable to wear, especially when moving around.
While more invasive signal capture methods, such as brain implants, are possible, research by Georgia Tech sought to create sensors that are easily placed and reliably manufactured.
