To provide a
biofeedback type smart headband that improves cognitive function, reduces
skin irritation, and is suitable for long-term wear. [Solution] The
biofeedback smart headband has a head-mounted main body structure. The main body structure integrates an electroencephalogram (EEG)
sensor array based on the theory of head regions in
traditional Chinese medicine, a galvanic
skin response (GDS) module based on the principles of meridians and acupoints, a
heart rate variability detection unit incorporating
pulse diagnosis theory, a low-power
microprocessor, and a tactile feedback mechanism simulating
acupuncture and
moxibustion stimulation. The electrodes of the EEG
sensor array correspond to the head
acupuncture stimulation areas of
traditional Chinese medicine, namely the Yintang and Shenting points in the
frontal region, the Taiyang and Zhugu points in the temporal region, and the Baihui and Fengchi points in the parieto-
occipital region. Dry
electrode technology is used to synchronously collect bioelectric signals from multiple brain regions and meridians. The GDS module's
measurement site is selected from the Laogong point on the hand or the heart region
reflex point on the ear. Flexible electrodes integrated into the ear hook and
conductive rubber electrodes on the front end of the main body form a
body surface meridian circuit. The GDS module uses an optical sensor to acquire
pulse wave signals from the
forehead, and the sampling frequency meets the dynamic detection needs of
traditional Chinese medicine pulse diagnosis. The tactile feedback mechanism includes vibration actuators distributed at positions corresponding to the Tou Wei and Si Shen So
acupuncture points, and simulates the qi-gaining
sensation of acupuncture and
moxibustion through vibration pulses of different frequencies.
