MIE Seminar Series: "photo-fueled soft robots and magnetic soft robots"


Friday, April 15, 2022 - 12:00pm

Soft robots have recently demonstrated joint-less curvilinear locomotion without the complex mechanical and electrical design principles of conventional robotic systems. Despite the successful demonstration of centimeter to meter scale pneumatic soft robots, their tethered power supply system would limit the working distance and complexity of the motion in case of miniaturized soft robots. Toward contactless manipulation of soft robots, photomotility and magnetomotility of polymeric materials will be discussed. To achieve photomotility, light active molecular machines are photopolymerized along with reactive liquid crystalline monomers. To achieve magnetomotility, magnetic particles are dispersed in elastomeric matrices and the micropillar arrays are prepared by a replica molding technique. In this presentation, I will discuss design strategy to program photo-fueled jumping of monolithic soft robots as well as synchronized magnetic actuation and collective self-assembly of micropillar arrays towards miniaturized and lightweight soft actuators.

Jeong Jae (JJ) Wie is currently Associate Professor in the Department of Polymer Science and Engineering and Program in Environmental and Polymer Engineering at Inha University, South Korea. He joined the faculty in 2015 following postdoctoral research at the United States Air Force Research Laboratory (AFRL) and at the Massachusetts Institute of Technology (MIT). He completed his Ph.D. degree in Department of Chemical Engineering from the University of Delaware in 2013. The breadth of his research interests includes untethered soft robotics, shape reconfigurable devices, inorganic polymers, and polymer nanocomposites.
