Low Perturbation BMI

Marc Ferro, Eric Zhao

Brain machine interfaces (BMIs) are playing an increasingly important role in neurological research, clinical treatments, and neuroprosthetics. With the advent of powerful signal processing and data analytics software tools, the impetus has shifted to developing implantable electrical probes with higher channel counts, lower tissue damage, long-term recording stability at the single cell level, and straight-forward implantation strategies. Previous generations of bulky, stiff electrodes are being replaced by a number of innovative new devices for lowering tissue damage, ultra-flexible meshes with chronic stability, flexible arrays, high channel counts and stretchable electrodes.

Our interest is developing bio-mimetic systems with dimensions and mechanical properties similar to axons already present in the brain. These ‘NeuroRoots’ are a new, low-damage method for precise implantation and high density recording.
