abstract

Medical ultrasound imaging is commonly used in hospitals and clinics for medical diagnosis. It is free from ionizing radiation (no risk of cancer), real-time, portable, and cost-effective. However, a conventional handheld ultrasonic imaging probe is bulky and not suitable for continuous and long-term monitoring of tissue dynamics. In this talk, firstly a single-element wearable ultrasonic sensor (WUS) composed of a polyvinylidene fluoride (PVDF) piezoelectric polymer film will be presented. The benefits of a flexible, lightweight, thin, and small size WUS are that it can be attached to a subject body for a long duration and can acquire data continuously without the intervention from an ultrasound operator. Then, its applications, including muscle motioning for the estimation of skeletal muscle contractile parameters, will be presented. The WUS technology could be a valuable tool for inexpensive, non-invasive, and continuous monitoring of the dynamical properties of soft tissues of interest.

biography

Yuu Ono (yuuono@sce.carleton.ca) is an Associate Professor with the Department of Systems and Computer Engineering, Carleton University, Ottawa, ON, Canada. He received his bachelor’s degree in electrical engineering from Tohoku University, Sendai, Japan in 1990 and his master’s degree in engineering and Ph.D. degree in electrical and communication engineering in 1992 and 1995, respectively, from the same university. His research interests include development of ultrasonic sensors and their applications for biomedical monitoring, diagnosis and control; tissue characterization; ultrasound signal and image processing; real-time monitoring, control and optimization of material processes; materials characterization; and non-destructive evaluation of products and structures. He is a professional engineer licensed in Ontario, a senior member of IEEE UFFC-S and EMBS, and a member of Canadian Medical Biological Engineering Society.
