Direct Data Interface (DDI)

Category-defining BCI

Direct data interface (DDI) is a BCI with both the data rate and the proximity to brain signals for advanced applications
Intracortical electrodes provide precise, single-neuron resolution that surface electrodes cannot
Current platform supports over 1600 intracortical channels for an industry-leading data rate
Massively scalable to support even more channels, higher data rates, and future enhanced capabilities

Cortical module

Direct, long-term access to brain data

Proven materials

Commonly used in similar medical devices, including titanium alloy body and platinum-iridium electrodes

Low-power/Low-noise

Patented on-chip processing to transform neural signals from analog to digital as close to the source as possible

Reliable

Hermetically sealed ceramic feedthroughs to protect electronics for long-term implantation

Tissue-friendly

Fine electrodes, each thinner than a strand of hair, limit tissue disruption

How it works

Real-time
DDI enabled communication

The Cortical Module, Internal Transceiver, and their connecting lead are surgically placed by a neurosurgeon using well-developed techniques commonly used in other surgical applications.

The Connexus DDI system includes the Cortical Module, Internal Transceiver, and the connected lead to transfer a continuous stream of data

How it works

Real-time
DDI enabled communication

The miniature microelectrodes on the Cortical Modules extend just below the brain’s surface to directly gather rich neural signals from the motor cortex.

How it works

Real-time
DDI enabled communication

This data passes from the Cortical Module to the Internal Transceiver along a thin, flexible lead. It is then wirelessly transmitted from the Internal Transceiver to a wearable External Transceiver via a secure optical data link. The system is continuously powered via an inductive couple.

How it works

Real-time
DDI enabled communication

This continuous stream of data then passes to a small computational unit that applies AI, machine learning, and advanced language models for real-time interpretation of the user’s intended speech or computer inputs.

User-Friendly

Designed for secure, reliable everyday use

The fully-concealed, implanted system provides complex data handling of brain data with no through-skin ports or wires.

A lightweight, unobtrusive wearable provides continuous wireless power and receives data securely using a near-infrared optical link.
