EEG-Driven Massage Headband For Anxiety Alleviation

In this paper, we report on the results of a recently proposed hardware design that uses neurological data analysis to identify and mitigate anxiety. The system uses a feedback-based network for stress relief, which includes a custom-built Electroencephalography (EEG) sensor, a massage motor circuit, Arduino pro mini board and massage motor. The network also includes an RGB LED that turns on when stress is detected. After signal amplification using differential amplifier and filtering, beta waves from the frontal regions can be effortlessly captured by skin electrodes and display on lcd. Three out of four subjects saw a successful reduction in elevated beta wave amplitudes, which are frequently linked to anxiety, by massage motor intervention. The motor smoothly turned on during the experimental sessions when beta amplitudes surpassed predetermined thresholds, encouraging relaxation and facilitating better task performance.
