For amputees to exploit the full capability of state-of-the-art prosthetic limbs with rapid fine-movement control and high-resolution sensory percepts, a nerve-interface with a large number of reliable and independent channels of motor and sensory information is needed. In this talk I will describe a novel approach that integrates multi-electrode thin-film polymer-metal electrode arrays into tissue-engineered biodegradable extracellular-matrix-based hydrogel nerve scaffold. This new class of neural interface, which we call Tissue-Engineered Electronic Nerve Interfaces (TEENI), has the potential to overcome major limitations of existing nerve interfaces (e.g., 1-D or 2-D electrode configurations that greatly undersample neural activity, low SNR, signal-attenuating tissue response, etc.). In this talk I will describe the design, fabrication, characterization, stress-testing, and preclinical assessment of our TEENI approach.

Dr. Jack Judy is a professor of Electrical and Computer Engineering, Biomedical Engineering, and Neurology at the University of Florida. He is also the Director of the Nanoscience Institute for Medical and Engineering Technology (NIMET) and holds the Intel Nanotechnology Chair. He was previously a Program Manager in the Microsystems Technology Office (MTO) of the Defense Advanced Research Projects Agency (DARPA) from 2009-2013, where he created and managed the Reliable Neural-Interface Technology Program (RE-NET) to address fundamental, and yet at the time largely overlooked at the time, critical reliability challenges of chronic neural-recording interfaces. He received the Ph.D. and M.S. degrees in electrical engineering from the University of California, Berkeley in 1996 and 1994, respectively and the B.S.E.E. degree from the University of Minnesota in 1989. His research interests are in the development of novel microscale and nanoscale sensors, actuators, and systems, and their use in impactful engineering, scientific, biological, and medical, applications. A particular focus is on the development of advanced and robust neural-interface technology components and systems for bi-directional prosthetic control and other applications. His honors include the National Science Foundation Career Award, the Okawa Foundation Award, and the Office of the Secretary of Defense Medal for Exceptional Public Service. He is a co-chair of the 2024 Gordon Research Conference (GRC) on Neuroelectronic Interfaces and the Program Chair of the 2025 International Conference on Solid-State Sensors, Actuators, and Microsystems.
