The findings related to the thought-control biosensor have been published in the journal “ACS Applied Nano Materials.” The 3D micropatterned sensor essentially reads EEG signals from the brain and, in the context of the announcement, allowed the person wearing it to control a quadruped robot. The sensors are attached to the scalp area, while the head-mounted display unit shows a pattern that users need to focus on for generating the controlling brain waves. As part of the tests conducted in partnership with the Australian Army, the team used an eight-channel HPEG sensor array that allowed controlling a quadruped robot with 94% accuracy.
The tech, as per the team, “offers the ability for the Australian Army to explore how soldiers interact with robotic systems during tactical missions.” Aside from defense, the brain-machine interface (BMI) tech can also be applied in manufacturing as well as the health sector where it can prove to be of critical help to people living with disabilities. However, the team still needs to work on a few areas like figuring out hair density, applying the right amount of contact pressure, and the available area for sticking the graphene sensors to get a stable signal reading.
