Research Interests: As director of The Laboratory of Neuroprosthetic Research, Dr. Troyk has a broad range of research interests related to neuroprostheses. Neuroprosthetic devices are implantable electronic modules that interface with the biological nervous system for the purpose of compensating for deficit, or disease, by mimicking normal sensory or motor function. Examples are neuromuscular stimulators for functional electrical stimulation (FES), implantable sensors for FES control, and cortical interfaces in which hundreds or thousands of electrodes sense and stimulate neurons within the central nervous system. The research work is highly interdisciplinary, using engineering principles and technology from electrical, computer, materials, mechanical, and chemical engineering. Design and fabrication of reliable implantable neuroprosthetic devices requires advancements in packaging of implantable electronics (hermetic and polymeric), VLSI integrated circuit design, transcutaneous magnetic coupling of power and data, as well as defining system architectures. He is leader of a large multi-institutional team working to develop an intracortical visual prosthesis for individuals with blindness. However, his other work includes industrial applications of remote wireless sensing and radio frequency identification (RFID). Current Projects Include: 1.
