Recently,remarkable advances have been made towards in vitro diagnostics on human skin or organ surfaces by integrating various functional components such as sensors,light emitting diodes,signal transmitters,etc.It is expected that such a wearable diagnostic and therapeutic device could transform the future "ubiquitous healthcare" (U-healthcare) in a new and innovative way.In order to achieve skin-attachable sensors,two components need to be suitably integrated: (1) an adhesive patch for stable fixation on the human skin or organ surface and (2) a bio-signal detection/wiring component for in vitro diagnostics.In this presentation,I will introduce our recent achievements on bio-inspired design and fabrication of dry adhesive skin patch and layered strain gauge sensor for in vitro diagnostics.Biographical Sketch Kahp-Yang Suh obtained his PhD degree from School of Chemical and Biological Engineering at Seoul National University (SNU) in 2002 and moved to MIT for postdoctoral research,working on the merger of micro- and nanofabrication technologies with tissue engineering and lab on a chip.He began his independent career in 2004 as Assistant Professor in Mechanical and Aerospace Engineering at SNU and was promoted to Full Professor in 2013.He is an associate editor of two international journals: Journal of Mechanical Science and Technology and Micro and Nano Systems Letters.Also,he served as an editorial board member for Lab on a chip journal for two years (2008-2009) and is currently an editorial board member of International Journal of Precision Engineering and Manufacturing,Journal of Bionic Engineering,and Journal of Sensor Science and Technology.He has more than 180 papers in peer-reviewed journals and holds 30 US or domestic patents.He won a number of awards,including TR100 Young Innovator Award (2004) by MIT Technology Review,Young Professor Award by College of Engineering of SNU (2007) and Young Researcher Award from the Korean Biochip Society (2008).More recently,he won the presidential young scientist award from the Korea Government (2010).His current research interests include (i) microfluidic platforms for single cell analysis and organ chips and (ii) nature-inspired functional surfaces such as gecko foot hairs and beetles wing locking device using various unconventional lithographic methods.
