Currently emerging biosensing and intracortical stimulation devices are promising alternative to allow studying the neural activity underlying cognitive functions and pathologies, understanding neurons interactions, locating seizures, detecting mind driven decisions, and achieve efficient treatment for these central neural systems. This talk covers low-power analog circuits and packaging techniques used for the design and integration of biosensing Microsystems. Such devices are interconnected to intracortical neural tissues, and include high-reliability wireless links used to power up such implanted devices and bidirectionally exchange data with external base station. Global view of typical devices altogether with corresponding multidimensional challenges will be described. Special attention will be paid to report two case studies: 1) Automatic detection of action potentials from massively parallel channels, and 2) Epilepsy seizures monitoring and onset treatment.


Mohamad Sawan received the B.Sc. degree in 1984 from Laval University, and the Ph.D. degree in 1990 in electrical engineering, from Sherbrooke University, Canada. He joined Polytechnique Montréal in 1991, where he is currently a Professor of Microelectronics and Biomedical Engineering. His scientific interests are the design and test of mixed-signal (analog, digital, RF, MEMS and optic) circuits and Microsystems: design, integration, assembly and validations. These topics are oriented toward the biomedical and telecommunications applications. Dr. Sawan is a holder of a Canada Research Chair in Smart Medical Devices. He is leading the Microsystems Strategic Alliance of Quebec (ReSMiQ) receiving membership support from 11 Universities. Dr. Sawan is Deputy Editor-in Chief of the IEEE Trans. on circuits and systems II (TCAS-II), Editor/ Associate Editor of several International Journals such as the IEEE Transactions on Biomedical Circuits and Systems (TBioCAS) and the Springer Mixed-signal Letters. He is founder / co-founder of several IEEE International conferences such as NEWCAS, BiOCAS, and ICECS, he is the founder of the Polystim Neurotechnologies Laboratory at Polytechnique Montréal. Dr. Sawan published more than 500 papers in peer reviewed journals and conference proceedings, and he was awarded 9 patents pertaining to the field of biomedical sensors and actuators. Dr. Sawan received several prestigious awards; the most important of them are the Medal of Honor from the President of Lebanon, the Bombardier Award for technology transfer, the Barbara Turnbull Award for medical research in Canada, and the achievement Award from the American University of Science and Technology. Dr. Sawan is Fellow of the IEEE, Fellow of the Canadian Academy of Engineering, Fellow of the Engineering Institute of Canada, and Officer of the Quebec’s National Order.
