Mechanics and Materials of Bio-Integrated Soft Electronics

Strategies for bio-integrated electronics must overcome challenges associated with the mismatch between the hard, planar surfaces of brittle semiconductor wafers and the soft, curvilinear tissues of dynamic biological systems. Although soft, flexible electronics have been developed by integrating inorganic functional materials strategically onto soft polymeric substrates, their performance and reliability are usually limited by the failure of stiff electronic materials such as metal, silicon and oxide under large deformation. This talk discusses the successful fabrication and bio-integration of tissue-like electronics that can conform to and deform with biology in an intimate manner. Two examples of bio-integrated electronics have been developed to manifest the power of such mechanistic understandings. Balloon catheters as minimally invasive surgery tools are instrumented with EKG, temperature and tactile sensors which can survive inflations as large as 200% and are tested within live animal models. As another example, ultra-thin, ultra-soft tattoo-like epidermal electronics are created to achieve conformal contact and compatible deformation with human skin for in vivo transcutaneous sensing and stimulation.

Bio: Dr. Lu joined the Department of Aerospace Engineering and Engineering Mechanics at The University of Texas at Austin as an Assistant Professor in August 2011. She received her Bachelor’s degree in Solid Mechanics from Tsinghua University in 2005. She obtained her Ph.D. in Mechanics of Materials from Harvard University in 2009. She then became a Beckman Postdoctoral Fellowship working on flexible electronics at the University of Illinois at Urbana-Champaign. Dr. Lu’s research focuses on the mechanics of flexible electronics including thin films on compliant substrates, micro-fabrication, and bio-integration. Her research has been highlighted by news media such as “Nature News”, “Science News”, “CNN News”, “BBC News”, and others. She is recently selected as one of the world’s top 35 innovators under the age of 35 by Technology Review Magazine.
