Abstract Scope |
Neuroprosthetics is a growing field rooted at the intersection of engineering and neuroscience targeting sensorimotor deficits related to stroke, spinal cord injury, and amputation. These systems rely on percutaneous or implanted electrodes, recording and/or stimulation electronics packages, a power source, and leads to connect the system. Typically, these systems operate with 16 channels of electrical signal or less, and commercial connecting components are generally limited to eight channels each. This presents a challenge for increasing channel counts to improve resolution and delivery of therapy. Furthermore, there is a need to be able to interchange components in case of failure or to facilitate implantation of upgraded technology, while leaving nerve electrodes or other implanted electronics intact. This work describes an effort to create a 32-channel, high-density, implantable in-line connector. Design, fabrication, and testing methodologies support this novel, scalable connector that leverages known biomaterials, minimizes implanted volume, and maintains desired electrical and mechanical performance. |
