SUMMARY:The School of Mechanical and Materials Engineering Seminar Series, “Shaping a Soft Future” Presented by Dr. Michael Dickey
LOCATION:Spark
DESCRIPTION:Shaping a Soft Future\n\nPresented by Dr. Michael Dickey, Camille & Henry Professor, Department of Chemical and Biomolecular Engineering, North Carolina State University\n\nAbstract:\n\nExisting devices—such as phones, computers, and robots – are made from rigid materials, which is in direct contrast to the soft materials that compose the human body. Our group is studying and harnessing soft materials to create devices (actuators, sensors, electronics) with tissue-like properties. For example, gallium-based liquid metal alloys have remarkable properties: low melting point, water-like viscosity, low-toxicity, and effectively zero vapor pressure.  Despite being liquid, these materials can be patterned into stretchable conductive circuits due to a thin, oxide skin that forms rapidly on its surface. This oxide can also be separated from the metal as a way to print thin conductors and dielectrics at ambient conditions.  In addition to soft electronic conductors, we study soft, stretchable ionic conductors called ‘ionogels’ that contain ionic liquids. We have found simple ways to improve the toughness of these materials. Taken together this work has implications for soft and stretchable electronics; that is, devices with desirable mechanical properties for human-machine interfacing, soft robotics, and wearable electronics.\n\nBiography:\n\nMichael Dickey received a BS in Chemical Engineering from Georgia Institute of Technology (1999) and a PhD from the University of Texas (2006) under the guidance of Professor Grant Willson. From 2006-2008 he was a post-doctoral fellow in the lab of Professor George Whitesides at Harvard University.  He is currently the Camille and Henry Dreyfus Professor in the Department of Chemical & Biomolecular Engineering at NC State University.  He completed a sabbatical at Microsoft in 2016 and EPFL in 2023.  Michael’s research interests include soft matter (liquid metals, gels, polymers) for soft and stretchable devices (electronics, energy harvesters, textiles, and soft robotics).  \n\n\n\n
