3D Printing Neural Interfaces with Exaddon µAM

High Aspect Ratio

Print high aspect ratio (100:1) structures directly on prepatterned traces or contact pads with micrometer accuracy. 

Cu or Au Micropillars

High conductivity pure metal needles and pillars, printed at room temperature with local electrodeposition. Pillars can be coated after printing. 

Fine Pitch Arrays

Pitch can be customized as needed. Image: 40 x 40 array of 1.6 μm diameter Cu pillars, printed at 25 μm pitch. 1600 pillars total.

                    An emerging discipline combining neuroscience and biomedical engineering, neuroprosthetics (often referred to as brain-machine or  brain-computer  interfaces, neural interfaces, or cortical implants) involves connecting external computing power to the brain via electrodes or implants in order to assist or replace human brain functionality, or simply to monitor brain activity.

                    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. 

                    Manufacturing tiny electrodes for implant into the brain is extremely challenging for conventional  technologies, but it is where Exaddon's 3D printing excels.

                    The CERES
                    system can 3D print electrode arrays in geometries impossible for other technologies, making it a unique solution for teams researching neural interfaces and electrodes. 

                    The incredibly precise electrochemical deposition results in high conductivity metal which is inherently biocompatible (Au). 

                    Micropillars can be printed with diameters as small as ~1 µm, and in arrays with customizable pitch.

                    CERES µAM print system is perfectly suited to creating conductive, mechanically stable electrodes.
