Elektrodok

Elektrodok is a term used in electrical and biomedical engineering to describe a modular electrode-docking system that provides a mechanical and electrical interface between electrode arrays and external hardware. The concept emphasizes a standardized, detachable connection that can accommodate various electrode chemistries and geometries, enabling rapid reconfiguration, testing, and replacement while maintaining sterility.

A typical elektrodok assembly comprises a docking module attached to the electrode array, a mating plug or spring-loaded contact array, and an enclosing shell that provides shielding and fluid sealing. The system is designed to preserve electrical impedance, minimize parasitic capacitance, and withstand saline environments. It aims to offer reliable signal transmission across multiple channels while allowing easy exchange of the electrode portion without disturbing the connected electronics.

Materials commonly used include biocompatible polymers such as PEEK or polyimide, and conductive elements of platinum-iridium or titanium. Surfaces may be passivated or coated with biocompatible layers. Connectors often feature impedance-matched, multi-pin configurations and may integrate short-range signal conditioning to reduce noise. The design also accounts for sterilization requirements and mechanical stability under movement or implantation conditions.

Applications span neuroscience research and clinical devices, including neural recording arrays, cortical or peripheral stimulation leads, and in vitro biosensing platforms. The elektrodok supports sterilization by ethylene oxide or gamma irradiation and can be reusable or designed for single-use depending on regulatory and economic considerations.

The term elektrodok is not universally standardized and may be used variably by manufacturers. It serves as a descriptive label for docking interfaces rather than a single universal product, reflecting a trend toward modular, plug-and-play electrode systems.
