New Approaches for Soft, Stretchable and Biomimetic Electronics for Advanced Sensors

Michael Dickey
Assistant Professor
Chemical and Biomolecular Engineering
North Carolina State University

Abstract
This talk will describe efforts from our research group to control the shape and thus function of soft materials (liquid metal, polymer and hydrogels) for applications that include sensors, soft/stretchable electronics, and self-folding polymer sheets. The research harnesses interfacial phenomena, microfabrication, and the unique properties of a moldable liquid metal. Conventional electronics are typically fabricated from rigid materials (e.g., silicon for transistors, copper for antennas). New materials are being explored as candidates for flexible/stretchable/ soft electronics because of the novel applications that emerge from their mechanical properties. Examples include flexible displays, implantable devices, electronic textiles, and soft robots. This talk will discuss the underlying fundamental science motivating active areas of research in our group and will included work on ultra-stretchable wires, sensors, antennas, and microelectrodes created by injecting a gallium-based metal alloy into elastomeric microchannels. Soft, biomimetic memory (“memristor-like”) and diode devices composed of hydrogels and moldable metal will also be discussed as well as self-folding polymers sheets that change shape in response to light.

Biography
Prof. Michael Dickey received a BS in Chemical Engineering from Georgia Institute of Technology (1999) and a PhD in Chemical Engineering from the University of Texas at Austin (2006) under the guidance of Professor Grant Willson. From 2006–2008 he was a postdoctoral fellow in the lab of Professor George Whitesides at Harvard University. Michael has several years of industrial work experience as a co-op for Kimberly Clark working on non-wovens and as a Chemical Engineer for Merck working on scaling up pharmaceutical processes. Prior to arriving at NC State Michael received several honors, including the Georgia Tech Presidents Scholarship, a NSF Graduate Fellowship, and a NIH Postdoctoral Fellowship. In August 2008, he joined the Department of Chemical & Biomolecular Engineering at NC State University where he is currently an Assistant Professor. He received the NSF CAREER award in 2010, the Sigma Xi Young Faculty Award in 2011, and the Outstanding Teacher Award in 2012. Michael’s research interests include the study of soft materials, thin films and interfaces, and unconventional nanofabrication techniques. The goal of the research is to introduce new functionality into devices (e.g., stretchable circuits, soft electronics, self-folding sheets) in a simple, inexpensive, and scalable manner.
