Customizable Handheld taVNS Controller Platform for OEM/ODM Product Development
This compact handheld taVNS controller is positioned as a configurable hardware platform for product developers, medical technology companies and wellness-device brands developing their own auricular stimulation products. The platform integrates a rechargeable lithium battery, USB charging, operating-status indication and an external ear-electrode interface within a portable handheld enclosure.
Unlike a fixed standard model with predefined operating programs, this platform can be developed around project-specific electrical output, control logic, electrode interface, housing appearance and accessory configuration. Heymed Medical supports customization from engineering evaluation and prototype development through private-label presentation and controlled production.
A Controller Platform Rather Than a Fixed-Function Device
For OEM and ODM development, the controller can be treated as a starting hardware architecture rather than a finished product with one mandatory operating configuration. Electrical output parameters, operating states, control logic and electrode connection can be reviewed according to the customer's intended product requirements.
This approach allows customers to develop different product variants from a common hardware concept while adapting the user interface, electrical configuration and accessory system for their own product program.
If a project requires a predefined production model instead, the GC-TVNS-A10 Portable taVNS / tVNS Device provides a more standardized configuration with three preset operating modes, adjustable intensity and 20-minute automatic session control.
Project-Specific Electrical Output and User Interface
Stimulation frequency, pulse width, waveform, output intensity, session timing and adjustment logic should be defined according to the approved specification of each project rather than assumed to be identical across different taVNS products.
The user interface can also be developed around the intended product workflow. Button functions, operating-status indication, parameter adjustment and display logic can be reviewed together with the electronic design and firmware requirements.
This gives device developers greater flexibility when building a product for a specific application, brand positioning or product-generation roadmap without simply reproducing the control logic of another commercially available device.
Flexible Ear Electrode Interface Development
The controller can be matched with different compatible auricular electrode structures according to the target product. Ear clip electrodes, earpiece-style electrodes and other project-specific contact structures can be evaluated together with the device-side electrical interface.
Connector type, pin assignment, polarity, channel configuration, conductive contact geometry and cable construction should all be confirmed as one complete device-to-electrode system.
Different reusable contact structures and cable configurations can be reviewed through our tVNS & taVNS Ear Electrodes range during product development.
OEM / ODM Development Options
Electrical configuration: Frequency, pulse width, waveform, intensity range and session-control logic can be defined according to the approved project requirements.
User interface: Button functions, operating logic, status indication and display content can be reviewed for customized product development.
Electrode system: Ear clip, earpiece and project-specific auricular electrode structures can be evaluated together with the controller.
Power architecture: Rechargeable battery capacity, charging method and power-management configuration can be developed according to the final product.
Industrial design: Housing color, surface finish, button arrangement, connector position and external appearance can be adapted to the approved design.
Private-label program: Logo, product labels, accessories, user documentation, carrying case and packaging can be configured for OEM/ODM projects.
Hardware, Electrode and Accessories Developed as One Product System
A portable taVNS product involves more than the controller itself. The electrical output, electrode interface, cable structure, charging accessories and physical product design all influence the completed system.
Customers can provide functional requirements, electrical specifications, industrial-design files, electrode concepts, connector definitions or an existing prototype for engineering evaluation. This allows the controller, cable and ear electrode to be reviewed together before the project enters prototype development.
For projects requiring additional cable or connector development, supporting interfaces can also be engineered through our Custom Medical Cable Assemblies capability.
Private-Label Device and Accessory Kit Development
The controller can be developed as part of a complete private-label product kit rather than supplied only as a standalone electronic unit. Depending on the project, the package may include the controller, compatible ear electrode, charging cable, contact accessories, user documentation and carrying or storage solution.
Product color, logo, labels, accessory combination, instruction materials and packaging artwork can be coordinated around the customer's brand and finished-product strategy.
Final claims, intended use, user instructions and destination-market compliance should be established according to the completed product and applicable regulatory pathway.
From Product Concept to Controlled Manufacturing
Development can begin from a product concept, functional requirement, electrical specification, industrial-design drawing or reference prototype. Heymed Medical can support feasibility review, hardware and interface evaluation, prototype preparation and engineering verification.
During the sample stage, electrical output, user-interface operation, battery and charging behavior, electrode connection, cable integration and mechanical assembly can be evaluated against the approved project specification.
Once the product configuration is confirmed, electronics assembly, enclosure production, cable and electrode manufacturing, inspection, branding and packaging can be transferred into controlled OEM/ODM production.
