Nervous system disorders represent one of the nation’s largest healthcare problems, afflicting more than 100 million people in the United States annually. Electrode arrays are emerging as premier neuroprosthetic interfaces for restoring sensory, motor, and other functions after nervous system damage or disease. While electrode arrays depend on action potentials to function properly, action potentials generated by nerves are relatively weak compared to surrounding physiological signals. This weakness obstructs clear array recording and stimulation.
University of Utah researchers have developed an electrically shielded containment system for high-count electrode arrays to combat signal contamination. This containment system consists of a gold screen that is connected electrically to ground and surrounds the array, reducing electrical noise contamination.
