Background
Currently, there are no commonly available hybrid devices combining bioelectrical and biooptical neurophysiological measurements, like electroencephalography (EEG) and functional near-infrared spectroscopy (nIRS). But the progressing fields of telemedicine, neurotechnology, and brain–computer interfaces, require wearable multimodal sensors of body- and brain-activity.
Technical Description
The mobile, modular, multimodal biosignal acquisition architecture (M3BA) offers high-performance and high precision acquisition of multiple bio-electrical and bio-optical brain- and body signals, including EEG, fNIRS and 3D-accelerometer. The instrument is wireless, miniaturized, fully customizable and energy efficient. It supports user-specified biopotential reference setups and wireless body area/sensor network scenarios.
This innovative technology is proofed by Physikalisch Technische Bundes-anstalt, a German calibration institut, and is tested in clinical trials.
Possible Applications
The technology is suitable for research and mobile clinical applications as well as for consumer or (car-)safety electronics or virtual reality applications.
