Abstract
Hard and soft structural composites found in biology provide inspiration for the design of advanced synthetic materials. Many examples of bio-inspired hard materials can be found in the literature; far less attention has been devoted to soft systems. Here we introduce deterministic routes to low modulus thin film materials with stress/strain responses that can be tailored precisely to match the non-linear properties of biological tissues, with application opportunities that range from soft biomedical devices to constructs for tissue engineering. The approach combines a low modulus matrix with an open, stretchable network as a structural reinforcement that can yield classes of composites with a wide range of desired mechanical responses, including anisotropic, spatially heterogeneous, hierarchical and self-similar designs. Demonstrative application examples in thin, skin-mounted electrophysiological sensors with mechanics precisely matched to the human epidermis and in soft, hydrogel-based vehicles for triggered drug release suggest their broad potential uses in biomedical devices.
Biography:
Yonggang Huang is the Joseph Cumming Professor of Mechanical Engineering and Civil and Environmental Engineering at Northwestern University. He has broad interests in many branches of Engineering Science and is interested in establishing mechanics models for advanced technology, such as stretchable and flexible electronics, inorganic solar cell, LEDs, cardiac and neural electro-physiological sensors, multifunctional catheters, epidermal electronics and transient electronics. Mechanics provides the scientific and engineering foundations and design guidelines for these stretchable and flexible devices. He has published 1 book and more than 400 journal papers and book chapters, including multi-disciplinary journals Science (2006, 2008, 2009, 2010, 2011, 2012, 2013, 2014) and its sister journal Science Translational Medicine (2010), Nature (2008, 2013) and its sister journals Nature Materials (2006, 2008, 2010a,b, 2011, 2013), Nature Nanotechnology (2006, 2013), Nature Neuroscience (2011) and Nature Communications (2012, 2013a,b, 2014a,b), and PNAS (2007, 2008, 2009, 2010, 2011a,b, 2012, 2013); and journals in physics (e.g., PRL), materials (e.g., Advanced Materials), nanotechnology (e.g., Nano Letters), biology (e.g., PLoS One), and 40 papers in the top mechanics JMPS. His recent work has been reported by many popular media such as ABC, BBC, Boston Globe, Business Week, CBS, Chicago Tribune, CNN, Discover Magazine, Discovery Channel, FOX, MSNBC, New York Times, Newsweek, Reuters, Scientific American, United Press International, and US News & World Report.
His recent awards include the Larson Award in 2003, Melville Medal in 2004, Richards Award in 2010, and Drucker Medal in 2013, all from ASME; Young Investigator Medal from the Society of Engineering Sciences in 2006; International Journal of Plasticity Medal in 2007; Guggenheim Fellowship from the John Simon Guggenheim Foundation in 2008; and ISI Highly Cited Researcher (Engineering) in 2009. He is the Editor-in-Chief of Theoretical and Applied Mechanics Letters, Editor of Journal of Applied Mechanics (Transactions of the American Society of Mechanical Engineers), and President of the Society of Engineering Sciences.
