Sunday May 10 Tutorial: 5:00pm – 5:40pm
"Intracortical Wireless Microsystems for Biosensing and Neurostimulation"
Professor Mohamed Sawan, Ecole Polytechnique de Montreal, Canada
This tutorial covers circuits and systems techniques for the integration and packaging of implantable biosensing and neurostimulation devices. Such Microsystems, dedicated for interconnections to intracortical neural tissues, are wirelessly powered up while bidirectional data are exchanged between them and external controllers. Global view of main devices will be described, case studies related to massively parallel recording of neural signals will be shown, and special attention will be paid to monitoring and microstimulation in the primary visual cortex through an optimized number of electrode arrays and power management of these bioelectronic devices.
Mohamad Sawan received the B.Sc. degree in electrical engineering from Université Laval, Quebec, Canada in 1984, the M.Sc. and Ph.D. degrees, both in electrical engineering, from Université de Sherbrooke, Sherbrooke, Quebec, Canada, in 1986 and 1990 respectively, and postdoctorate training from McGill University, Montréal, Quebec, Canada in 1991. He joined Ecole Polytechnique de Montréal in 1991 where he is currently a Professor in Microelectronics. His scientific interests are the design and test of mixed-signal (analog, digital and RF) circuits and systems, the digital and analog signal processing, the modeling, design, integration, assembly and validation of advanced wirelessely powered and controlled monitoring and measurement techniques. These topics are oriented toward the biomedical implantable devices and telecommunications applications. Dr. Sawan is a holder of a Canadian Research Chair in Smart Medical Devices. He is leading the ReSMiQ (Microelectronics Strategic Alliance of Quebec) research center known and the Eastern Canadian IEEE-Solid State Circuits Society Chapter. Also, he is cofounder of the International Functional Electrical Stimulation Society, founder of PolySTIM neurotechnology laboratory at the Ecole Polytechnique de Montreal, and founder of the Northeastern workshop on Circuits And Systems (NewCAS). He received many awards for academic excellence and he is cofounder of a Canadian biomedical technology company Cortivision. He received the Barbara Turnbull 2003 award for spinal cord research, he is Fellow of the Canadian Academy of Engineering and Fellow of the IEEE.
