Slight skin penetration increased signal quality
“I started this research because my main goal is to develop new sensor technology to support health care. I had previous experience with brain-computer interfaces and flexible scalp electronics,” said Hong Yeo, professor at Georgia Tech’s George W. Woodruff School of Mechanical Engineering.
“We needed better BCI sensor technology and discovered that if we can slightly penetrate the skin and avoid hair by miniaturizing the sensor, we can dramatically increase the signal quality by getting closer to the source of the signals and reduce unwanted noise,” he added.
