Reference number : GC-2017-Q1-00569, amendment number : , agreement type : G, recipient legal name : Nabki, Frederic (École de technologie supérieure), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Engage Plus Grants for Universities, program name french : Subvention d'engagement partenarial Plus pour les universités, program purpose english : Ultrasonic transducers are seeing widespread use in low-intensity applications such as medical imaging,_x000D_
non-destructive testing and ranging, or in high-intensity ones like cleaning and liquid emulsification. For_x000D_
decades, piezoelectric transducers have been the workhorse in ultrasonics. However, micro-machined_x000D_
capacitive transducers are currently attracting significant interest. A unique advantage over their bulk_x000D_
piezoelectric counterpart lies in their lower mechanical impedance, offering the potential for a better_x000D_
impedance match with low-density fluidic media such as air. The operation of such transducers is also much_x000D_
less sensitive to temperature. Capacitive micromachined ultrasonic transducers (CMUTs) are usually integrated_x000D_
closely with their interface electronic circuits forming complete stand-alone ultra-compact systems. This can_x000D_
allow ultrasonic systems to be integrated into handheld devices. The research group of Prof. Nabki has_x000D_
developed a novel Silicon Carbide CMUT, and demonstrated a proof of concept prototype showcasing the_x000D_
device's potential, and gaining the interest of Olympus Corporation, an international company with many R&D_x000D_
operations in Canada. Olympus operates in industrial, medical and consumer markets, and specializes in optics,_x000D_
electronics and precision engineering, with products deployed in Canada and around the world. Notably,_x000D_
Olympus is a world-leading manufacturer of innovative non-destructive testing (NDT) instruments that are_x000D_
used in industrial and research applications. It has a large operation in Quebec City of about 400 people, which_x000D_
handles R & D and production._x000D_
Throughout this Engage Plus project, Olympus is planning to expand its extensive testing plans of the_x000D_
previously fabricated CMUTs as part of a previous Engage project. The characterization will include flaw_x000D_
detection, beam profiling, and uniformity inspection. A second fabrication run will be performed to optimize_x000D_
the CMUT's performance and durability. Finally, a demonstration kit will be developed for a smartphone that_x000D_
includes both the 5 MHz and 15 MHz CMUTs. This project will provide training for two Ph.D. students., program purpose french : Ultrasonic transducers are seeing widespread use in low-intensity applications such as medical imaging,_x000D_
