AI Technical Summary

Technical Problem

Existing vagus nerve stimulation techniques for the ear suffer from problems such as low positioning accuracy, poor parameter adaptability, insufficient comfort during long-term wear, and excessive impedance of electrode materials, resulting in poor stimulation effects and unpleasant patient experience.

Method used

Design an ear vagus nerve stimulation electrode that includes a shell structure and an electrode structure. The shell structure consists of an upper shell, a lower shell, a top cover, and a cover plate. An auricular cymba electrode is placed on the upper shell and an auricular tragus electrode is placed on the lower shell. A combination of conductive silicone layer and copper nut is used to achieve precise fit through a bending structure. Electrical conduction is achieved by combining wires and solder points, and the electrodes can be rotated and adjusted to adapt to different ear structures.

Benefits of technology

It improves the targeting and comfort of vagus nerve stimulation in the ear, simplifies the operation process, reduces impedance values, and enhances the user experience and electrode stability.
