Background Vagal nerve stimulation (Vagus Nerve Stimulation, VNS) has been widely used as a neuromodulation technique in the treatment and rehabilitation of epilepsy, depression, and other diseases. Conventional vagus nerve stimulators are mostly implantable devices. Although the effect of the equipment is clear, the equipment has the problems of large operation wound, high cost, high infection risk and the like, and limits the application range of the equipment. To reduce the threshold of use and avoid the risk of surgery, non-invasive vagal nerve stimulation techniques have been developed. Currently, the non-invasive vagus nerve stimulator mainly stimulates the vagus nerve branches of the ear, and the device is usually designed as an ear clip type or an earphone type. However, the stimulation of the vagus nerve at the ear has the limitations that the stimulation target point is indirect, the stimulation effect is weaker than that of the vagus nerve stem at the neck directly, and the like.
