2-Pole Conductive Silicone taVNS Ear Clip Electrode

A reusable two-pole conductive silicone ear clip electrode developed for taVNS and tVNS device manufacturers that need a compact auricular contact, integrated cable and device-specific connector. Goochain can supply the standard configuration or review changes to contact geometry, cable length, cable jacket, connector and packaging for a custom project.

Key Features

• Two conductive silicone contact poles in a compact ear-clip form.
• Designed for auricular / tragus-area stimulation-device applications.
• Typical 1.2 m cable configuration, with project-specific length options.
• 2.35 mm safety connector option; other connector formats can be evaluated.
• Cable, connector, contact geometry, color and packaging customization subject to engineering review.
• EU Registered Community Design No. 015144558-001 for the applicable configuration.

Typical Specification

Design Details That Matter

Two-Pole Contact Arrangement

The bipolar contact arrangement places two conductive silicone contact surfaces within the ear-clip structure. Contact spacing, usable surface, pressure and alignment should be evaluated together with the device output and intended ear position.

Cable Exit and Strain Relief

Cable movement can apply torque to a small wearable electrode. The cable exit direction, conductor construction, jacket flexibility and strain relief should therefore be selected as a system. Goochain can review cable length and exit requirements around the intended use and packaging route.

Connector Integration

The connector must match more than the visible socket shape. Pinout, polarity, conductor assignment, mechanical insertion, retention and device output all require review. A USB-C-shaped connector does not by itself indicate USB protocol or compatibility with a consumer charging port.

Customization Options

Quality and Project Validation

Goochain's medical accessory manufacturing is supported by ISO 13485 and ISO 9001 quality management systems. Project documentation can be aligned with agreed customer requirements, including drawings, material records, inspection points, traceability and sample approval.

Depending on the project, relevant checks may include dimensions, visual workmanship, cable continuity, connector retention, repeated flexing, contact consistency, cleaning exposure, packaging and representative fit evaluation. Test methods and acceptance criteria should be defined for the final device and intended use.

Applications

• Wearable taVNS / tVNS devices
• Auricular neurostimulation research and development systems
• External stimulation accessory kits
• Device-manufacturer replacement and service programs

Frequently Asked Questions

Is this ear clip universally compatible?

No. Connector shape alone is not sufficient. Pinout, polarity, electrical output, contact arrangement and mechanical fit must be matched and validated for the target device.

Can I order the ear clip with another connector?

Yes. Goochain can review 3.5 mm, USB-C form factors and other project-specific interfaces. Please provide the mating connector or drawing, pinout and electrical requirements.

Can the cable be shorter or longer?

Yes. The typical configuration uses a 1.2 m cable, but project-specific length, jacket, color and exit requirements can be evaluated.

Can the contact geometry be changed?

Yes, subject to the target ear position, mechanical envelope, tooling, material and validation requirements. A custom configuration may require a development project.

What should I send for a quotation?

Send the target ear position, connector and pinout, output parameters, cable length, estimated prototype and annual volume, target market, packaging and required quality documents.
