Speaker: Luc Fréchette, Université de Sherbrooke, Canada

— Abstract — La vision de l’internet des objets connectés promet des milliards de capteurs sans fils interconnectés et distribués autours de nous pour rendre notre environnement plus sécuritaire, efficace énergétiquement et convivial. Mais qui voudra changer les piles dans ses capteurs sans fils? Afin de palier au défis énergétiques pour l’alimentation des capteurs sans fils, des microsystèmes de récupération d’énergie ont été proposés, puisant leur énergie des vibrations et gradients de température environnants.  Nous présenterons les avancées récentes dans le développement des microrésonnateurs piézoélectriques ainsi que des micromoteur fluidiques pour la récupération de chaleur, tout en indiquant leur potentiel pour répondre aux besoins des capteurs sans fils.

k2_smallTitle: The Coming of Age of Microfluidics: Connecting Algorithms and Foundations of Chip Design to Biochemistry and the Life Sciences
Speaker: Tsung-Yi Ho, National Tsing Hua University, Taiwan.

— Abstract — This seminar offers attendees an opportunity to bridge the semiconductor ICs/system industry with the biomedical and pharmaceutical industries. This talk will first describe emerging applications in biology and biochemistry that can benefit from advances in electronic “biochips”. The presenters will next describe technology platforms for accomplishing “biochemistry on a chip”, and introduce the audience to both the droplet-based “digital” microfluidics based on electrowetting actuation and flow-based “continuous” microfluidics based on microvalve technology. Next, the presenters will describe system-level synthesis includes operation scheduling and resource binding algorithms, and physical-level synthesis includes placement and routing optimizations. In this way, the audience will see how a “biochip compiler” can translate protocol descriptions provided by an end user (e.g., a chemist or a nurse at a doctor’s clinic) to a set of optimized and executable fluidic instructions that will run on the underlying microfluidic platform. The problem of mapping a small number of chip pins to a large number of array electrodes will also be covered. Finally, sensor feedback-based cyberphysical adaptation will be covered.

He has been the recipient of the Invitational Fellowship of the Japan Society for the Promotion of Science (JSPS), the Humboldt Research Fellowship by the Alexander von Humboldt Foundation, and the Hans Fischer Fellow by the Institute of Advanced Study of the Technical University of Munich. He was a recipient of the Best Paper Awards at the VLSI Test Symposium (VTS) in 2013 and IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems in 2015. He served as a Distinguished Visitor of the IEEE Computer Society for 2013-2015, the Chair of the IEEE Computer Society Tainan Chapter for 2013-2015, and the Chair of the ACM SIGDA Taiwan Chapter for 2014-2015. Currently he serves as an ACM Distinguished Speaker, a Distinguished Lecturer of the IEEE CAS Society, and Associate Editor of the ACM Journal on Emerging Technologies in Computing Systems, IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, and IEEE Transactions on Very Large Scale Integration Systems, Guest Editor of IEEE Design & Test of Computers, and the Technical Program Committees of major conferences, including DAC, ICCAD, DATE, ASP-DAC, ISPD, ICCD, etc.

jhossain_smallTitle: Wireless Communications with Energy Harvesting Nodes
Speaker: Jahangir Hossain, University of British Columbia, Canada

— Abstract — Wireless nodes (WNs) usually have limited storage capacity of the batteries. The limited battery and high transmit power may result in the quick drainage of the batteries. As a result, the batteries need to be periodically replaced or recharged, which can be impractical. For example, wireless sensor nodes can be placed in a toxic or hazardous environment that prohibits human intervention. In these situations, deploying energy harvesting (EH) nodes is an alternative solution. EH nodes can be regarded as a promising option for deployment as they ensure a long system lifetime without the need for periodic battery replacements. However, using EH nodes for conventional communication systems is not straightforward and requires a careful attention to design communication devices and to develop communication protocols and resource control algorithms. This talk will explore some design and optimization problems for EH systems and delve into their performance analysis.

— Bio — Dr. Jahangir Hossain (S’04-M’08) received his M.A.Sc. degree from the University of Victoria, Victoria, BC in 2003 and his Ph.D. degree from the University of British Columbia (UBC), Vancouver, BC in 2007. He is currently working as an Associate Professor in the School of Engineering, UBC, Okanagan Campus. His research interests include developing energy and spectrally efficient physical (PHY) and medium access control (MAC) layer technologies for wireless systems. Dr. Hossain regularly serves as a member of the Technical Program Committee of the IEEE International Conference on Communications (ICC). He served as an Editor for the IEEE Transactions on Wireless Communications from 2009 to 2014.
