About the project
The main goal of this project is to investigate and design novel electrodes for minimally invasive brain sensing.
This will be modelled in COMSOL to ensure high spatial and temporal resolution in brain sensing, which consequently lead to the robust interpretation and decoding of brain signals. The fabricated electrodes will be later integrated in a brain phantom for proof of concept. Moreover, these electrode nodes will also feature electrical stimulation capabilities, thereby giving rise to a bidirectional distributed neural interface.
Minimally invasive brain-machine interfacing (MiBMI) establishes a direct communication pathway between the brain and external devices with minimal disruption to the brain or surrounding tissues. These approaches aim to reduce surgical risks, recovery times, and complications while maintaining or improving the accuracy and functionality of the interface.
Brain stents, also known as intracranial stents, are tiny mesh-like medical devices designed to be inserted into blood vessels within the brain. These stents help improve blood flow or support the structure of the blood vessels. Stentrodes, or brain stents containing arrays of electrodes, have recently been developed and proven to be safe and appealing substitutes for open brain surgery that involves inserting brain-machine interface electrodes such as Utah Array or Neuropixels. Using Stentrodes, it is possible to record brain activities from a blood vessel, enabling MiBMI.
