When a portable taVNS device moves from a sample to a finished product, the ear contact and lead deserve as much attention as the controller. Goochain will bring these parts together at the 94th China International Medical Equipment Fair (CMEF) in Beijing, October 21–24, 2026. Visitors can find Dongguan Goochain Technology Co., Ltd. at Booth A1-ZC38 in the Capital International Exhibition & Convention Center, where the team will discuss practical choices around electrodes, cables and device integration.

What visitors can examine at the stand

The invitation features a portable taVNS controller connected to an ear-worn electrode, with several ear clip forms shown alongside it. Visitors can examine how the controller, lead and ear contact come together as a physical product. Goochain’s portable taVNS device page offers a closer look at one device platform ahead of the show.

An ear clip is a small part that sets the relationship between the device and the user. Its shape affects where the contact sits; its cable exit affects how the lead moves when worn; and its mating connector has to work with the electronics on the other end. At the booth, we can put the samples side by side and discuss which features matter for a visitor’s intended design. The pictured variants give visitors concrete forms to compare and questions to raise about their own projects.

The design questions behind an ear electrode

A team refining an existing device may arrive with a contact that needs a different profile. Another may have a working controller but still be deciding between an ear clip and an earpiece, or between cable lengths and connector formats. Our reusable taVNS ear clip electrode is one example of the types of parts we can discuss. The useful questions are specific: How is the electrode positioned? What is the intended cleaning or replacement approach? Where does the cable need to run, and what must connect at the device end?

Those answers help define the next sample. Goochain welcomes drawings, photographs, connector information or an existing part at A1-ZC38 so the conversation can start with the actual constraints. If a project is early, even a rough outline of the device housing and intended wearing position helps identify what should be checked first.

From a sample to an integrated assembly

For OEM and ODM teams, the discussion can follow the route from the ear contact to the controller: lead length, strain relief, connector mating, overmold shape, and assembly checks. These project questions can be reviewed against a customer’s drawings and requirements. A connector position that works on the bench, for example, may call for a different lead direction once the housing and wearing position are defined.

Goochain also works with medical cable assemblies. That makes it possible to talk about the electrode and lead as one assembly when a customer is planning a new prototype or revising an existing accessory. Visitors who bring a current sample can point out exactly what should be retained and what needs to change before a sample build is scoped.

Plan a visit to A1-ZC38

The 94th CMEF takes place October 21–24, 2026, at the Capital International Exhibition & Convention Center in Beijing. Goochain’s booth is A1-ZC38. Whether the question is about a portable taVNS platform, an ear contact or the cable between them, visitors are welcome to bring the details to the stand and discuss the next practical step with our team.
