The recent development of multimaterial fibers has enabled devices with unprecedented properties and functionalities. Here I present these fiber devices for biomedical and wearable applications. Current neural interface devices are mostly based on hard materials which can cause significant tissue damage. Using a thermal fiber drawing process, we have developed flexible multifunctional fibers for simultaneous electrical, optical and chemical communication with neural circuits in deep brain with minimal tissue damage. Moreover, flexible pressure sensors that can map pressure distributions is of great importance to various applications. Here we have developed a distributed pressure sensing fiber using frequency domain reflectometry. These fibers can also be woven into a fabric for pressure mapping applications such as touch pads, car seats, and wearables. 


Xiaoting Jia is an assistant professor in the Bradley Department of Electrical and Computer Engineering at Virginia Tech. Before joining Virginia Tech she was a postdoctoral associate in the Research Laboratory of Electronics at MIT. She received her PhD from MIT (2011) and MS from Stony Brook University (2006), both in Materials Science and Engineering, and BS in Materials Science from Fudan University in China (2004). She has authored and coauthored 32 papers published in journals including Science, Nature Biotechnology, and Nature Neuroscience, with over 10,000 citations. She was the recipient of an NSF CAREER Award, 3M Non-Tenured Faculty Award, and ICTAS Junior Faculty Award at Virginia Tech, and was the Translational Fellow at MIT.
