Abstract
Brain Computer Interfacing is a sprawling scientific field, with many competing designs in use or being tested. The goal of this project was to compile information about Utah Arrays, Michigan Probes, Neural Lace (also known as Mesh Electronics), Neuralink and Stentrode, and compare the positives and negatives of each design. Of especial interest were the parameters of material, number of electrodes, severity of foreign body response, heat generation, electrode depth, average size of measured action potentials and signal to noise ratio. The results of this comparison was as follows: Mesh Electronics and Stentrode are highly promising due to the complete avoidance of traditional foreign body response and cell death issues, however the latter...

Brain Computer Interfacing is a sprawling scientific field, with many competing designs in use or being tested. The goal of this project was to compile information about Utah Arrays, Michigan Probes, Neural Lace (also known as Mesh Electronics), Neuralink and Stentrode, and compare the positives and negatives of each design. Of especial interest were the parameters of material, number of electrodes, severity of foreign body response, heat generation, electrode depth, average size of measured action potentials and signal to noise ratio. The results of this comparison was as follows: Mesh Electronics and Stentrode are highly promising due to the complete avoidance of traditional foreign body response and cell death issues, however the latter trades these for the risks of long term usage of anti-coagulants. Utah Arrays have more problems than any of the other investigated designs in all parameters, including the contemporary Michigan Probe, although they both use the same primary material, silicon. There was found to be a severe lack of experimental studies rigorously comparing these two designs to each other, a lack that may become even more glaring once more of these designs become available for further medical studies.
