Philip R. Troyk is Executive Director, Pritzker Institute of Biomedical Science and Engineering, Professor of Biomedical Engineering, Affiliate Professor, Stuart School of Business at the Illinois Institute of Technology, and Faculty Associate, Division of Biological Sciences 鈥 Department of Neurosurgery at The University of 电车无码. He is founder, president, and CEO of Sigenics, Inc. Sigenics is the only private-label custom semiconductor company headquartered in 电车无码, with offices in 电车无码 and Irwindale, CA.

Academically, Troyk has a broad range of research interests related to neuroprosthetic devices which 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 stimulating paralyzed muscles, implanted sensors for control of prosthetic limbs, neural interfaces for bioelectronics medicines, and brain interfaces. He is leader of a large multi-institutional team working to develop an intracortical visual prosthesis for individuals with blindness. His work is highly cross-disciplinary, and incorporates novel methods of design innovation and marketing-type decision processes. As CEO of Sigenics, he leads an engineering organization that supplies 250,000 custom electronic chips/year placed in modules that control on-board avionics for Boeing and Airbus planes, as well as develops chips that are in medical clinical trials for implantable neural interfaces devices.

His interests include structured methods of design that focus heavily upon customer involvement, and highly-adaptable project management methodologies.

Research Interests

Design of implantable electronic devices and systems to act as neural interfaces. The interfaces provide communication to, and from, the central and peripheral nervous system for the purposes of compensating for neuromuscular deficit and disease.

Current Projects

Intracortical Visual Prosthesis 鈥 A system of modules to be implanted into the brain for restoration of visual sensation for people with blindness. The micro-sized wireless implanted devices communicate image information directly to the brain.

Sensors for Prosthetic Limb Control - Implantable myoelectric sensors (IMES) for sensing motor commands to control prosthetic limbs. The wireless grain-of-rice sized sensors transmit muscle commands directly to an artificial limb.

Bioelectronic Medicine Interfaces 鈥 Devices that provide sensing, stimulation, and blocking of autonomic peripheral nerves in order to act as a substitute for pharmacological-based therapies. The neural activity is modulated to facilitate improved organ function for diseases such as hypertension, incontinence, asthma, and chronic pain.
