Abstract
Advancements in neural interfaces are pivotal for enhancing the functionality and longevity of implantable biomedical applications, particularly in the field of neuroprosthetics. This dissertation is focused on the continuing development of a novel neural interface fabricated from silicon carbide (SiC). SiC has demonstrated superior performance over traditional silicon-based material systems due to its exceptional biocompatibility, hemocompatibility, and electrochemical stability. The research herein explores silicon carbide’s semiconductor properties, with a highlighted focus on a unique and innovative design structure - centered around a p-n junction. This work examines detailed fabrication steps of an all-SiC device, acute-style packaging (for future in vivo experiments), electrochemical testing, human cadaver peripheral nervous system studies, as well as a look ahead to in vivo recording and stimulation in the near future. Ultimately, this dissertation brings the development of the silicon carbide based neural interface one step closer to demonstrating long-term efficacy in bionic limbs and other neurotechnology applications.
