报告摘要：Recently, hydrogels have been intensively studied to develop stretchable electronics for wearables and soft robots. In this talk, I will present our research on developing novel ionic hydrogel-based sensors for wearable sensing and soft robotics. The research has been focused on designing novel ionic hydrogel-based sensors, investigating response characterization of sensors, and develop advanced control methods. These efforts provide a new paradigm for developing high-performance artificial skins for strain sensing on both human body and winter coat, human–machine interaction, motion/deformation sensing on a soft gripper and a soft robot. The ionic hydrogel-based sensors I will discuss include: (i) a sensing solution based on ionic hydrogel for soft robotics，including fabricating the hydrogel sensor, investigating durability and response characterization of our hydrogel sensor; (ii) a LSTM model for object recognition; (iii) a design of closed-loop PID force controller. In closing, our ongoing efforts on different sample testing of soft robot will also be briefly outlined.

报告人简介：Xinyu Liu is currently the Percy Edward Hart Professor with the Department of Mechanical and Industrial Engineering and is cross-appointed with the Institute of Biomedical Engineering, University of Toronto. Before joining the University of Toronto, he was an Associate Professor and the Canada Research Chair with the Department of Mechanical Engineering, McGill University. He obtained his B.Eng. and M.Eng. from Harbin Institute of Technology in 2002 and 2004, respectively, and his Ph.D. from the University of Toronto in 2009, all in Mechanical Engineering. He then completed an NSERC Postdoctoral Fellowship in the Department of Chemistry and Chemical Biology (with George Whitesides) at Harvard University in 2009–2011. At U of T, his research activities primarily focus on microfluidics, bioMEMS, and micro/nanorobotics, with applications in medicine and biology. He was a recipient of the Stars in Global Health Award from Grand Challenges Canada (2012), the Douglas R. Colton Medal for Research Excellence from CMC Microsystems (2013), the Christophe Pierre Award for Research Excellence from McGill University (2017), and the Young Scientist Award from the Microsystems & Nanoengineering Summit (2018), the Highly Cited Paper Award from Microsystems & Nanoengineering (2020), and the Outstanding Paper Award from Materials Horizons (2020). He is a Senior Editor of IEEE ROBOTICS AND AUTOMATION LETTERS and Microsystems & Nanoengineering, and an Associate Editor of IEEE TRANSACTIONS ON AUTOMATION SCIENCE AND ENGINEERING, IEEE TRANSACTIONS ON NANOTECHNOLOGY, International Journal of Advanced Robotic Systems, and IET Cyber-Systems and Robotics. He also served on the Editorial Boards of the three major IEEE Robotics and Automation Society Conferences (ICRA, IROS, and CASE).
