Technology

We use graphene to build high-resolution brain interfaces

We have developed a novel type of graphene-based transistors combining all the features required to build high-resolution brain-computer interfaces with multiplexing capabilities and sensitivity across a wide range of frequencies.
We circumvented the bottlenecks faced by other approaches thanks to the unique properties of graphene.

Project

We’re joining forces to meet this challenge

GphT-BCI project paves the way for the clinical translation of graphene transistors for brain-computer interfaces. To achieve our ambitious objectives, we have put together an interdisciplinary consortium formed by a high-renowned research center and a high-promising SME, with all the expertise and resources needed to complete the project within time and budget.

Roadmap

We are preparing to bring neural interfaces into the clinic.

This project will pave the way for the clinical translation of brain mapping neural interfaces based on graphene-based transistor arrays for brain-computer interfaces.

1

Creating pre-surgical and intraoperative neuronal mapping of the brain.

The first application of our ground-breaking technology will be neural presurgical and intraoperative acute brain mapping. Our graphene-based transistor leads can be used to monitor tissue functionality and guide neurosurgeons during localization and resective interventions.

2

Building high-resolution brain interfaces

Then, we will advance towards brain-computer interfaces with chronic ultra-high-resolution decoding capabilities, with applications in Parkinson, Epilepsy and Stroke (Aphasia, speech synthesis).

3

Integrating elements into a standalone patient platform

These will come with an implantable interface and communication system and a patient closed-loop communication app.
