O Abstract: The human body is mechanically soft with a complex 3D curvilinear shape; modern electronic and microfluidic technologies are rigid with static 2D layouts. Eliminating this discrepancy in physical properties creates enormous opportunities in artificial systems that can be closely integrated with the human body for diagnostic and therapeutic with important and unique functions in health/wellness, sports performance, and clinical health care. Over the last decade, a convergence of new concepts in electrical engineering, mechanical engineering, and materials science has led to the emergence of diverse, novel classes of skin-interfaced electrical systems with skin-like physical properties. This seminar describes the key ideas and presents some of the most recent device examples, including (1) wireless skin-interfaced devices for a cardiopulmonary monitoring system or for measurement of itching, (2) sensor networks for quantifying full-body movement behaviors with multiple devices, and (3) sensors for real-time monitoring and patient feedback on respiratory and swallowing biomechanics.

O Short Bio: Dr. Youn Joung Kang is an assistant professor of the department of Ocean System Engineering at Jeju National University. Prior to joining Jeju National University, she was a postdoc at Northwestern University, USA. She received the BS degree in Electrical Engineering in 2006 from KAIST, MS degree in Ocean System Engineering in 2014 from Jeju National University, and Ph.D degree in Mechanical Engineering 2020 from KAIST. She gave the representative speech at 2020 KAIST commencement. Her main research focus is on biofluidics, which analyzes the fluid dynamic signals occurring inside the human body, i.e. heartbeat, blood pressure, swallowing, and so on. She also received the Best presentation student award for outstanding research in the 15th Asian Symposium on Visualization
