Neuroprosthetics & Brain-Machine Interfaces

Utilizing Additive Manufacturing

An emerging discipline combining neuroscience and biomedical engineering, neuroprosthetics (often referred to as brain-machine interfaces or brain-computer interfaces) involves the use of external computing power to either assist or replace human brain functionality.

Through the placement of an electrode sensor on the brain, these brain-machine interfaces enable functions which are no longer possible by the human body. An increasing number of highly innovative companies are improving the lives of people suffering from hugely disempowering conditions such as Parkinson's or Alzheimer's, through use of implantable devices which are linked to external computers.

These devices require tiny electrodes to be implanted into the brain, and this presents challenges. Exaddon's CERES µAM print system can 3D print microscale electrodes and electrode arrays with high conductivity in geometries impossible for any other technology, making it an ideal solution for teams researching BCIs.

CERES works through incredibly precise electrochemical deposition of ionic metals on different substrates, including flexible polymers like PEDOT:PSS. These offer great potential in neuroprosthetic applications such as brain-computer interfaces.

Exaddon’s unique additive micromanufacturing technology allows printing of micropillars in high-conductivity, pure metal, such as copper or gold. With object diameters possible below 1 µm, the CERES µAM print system is well-suited to creating complex and tiny structures necessary for conductive, mechanically stable electrodes.
