"Large-scale Manufacturing of Wearable Electronics and Flexible Plasmonic Devices"


Traditional manufacturing methods and materials used to fabricate photonics and epidermal electronics for physiological monitoring, transdermal stimulation, and therapeutics are complex and expensive, preventing their adoption as single-use medical devices.  This talk will describe large-scale manufacturing approaches to print nanostructures and electrochemical paper-based electronic devices for wearable and implantable applications by combining the spray-based deposition of silanizing agents, highly conductive nanoparticles, and encapsulating polymers, with laser micromachining.  These devices are inexpensive, stretchable, easy to apply, and disposable by burning.  The omniphobic character and fibrous structure of their paper substrate make these sensors breathable, mechanically stable upon stretching, and facilitate their use as electrophysiological sensors to record electrocardiograms, electromyograms, and electrooculograms, even under water.  Further demonstrations of this technology include inexpensive devices for point-of-care diagnostics, monitoring wound status, providing thermotherapeutic treatments to joints, and the wireless powering of implantable devices for stimulation and therapeutics.  These examples will serve to illustrate a paper-based approach to make epidermal electronic devices accessible to high-throughput manufacturing technologies in order to enable the fabrication of a variety of wearable medical devices at a low cost.

Ramses V. Martinez has been an assistant professor at the School of Industrial Engineering and the Weldon School of Biomedical Engineering at Purdue University since January 2015. His research group, the FlexiLab, is primarily involved in several projects in the areas of nanomanufacturing, biosensing, and soft robotics. Dr. Martinez grew up in Madrid, Spain, and received a degree in Applied Physics from the Universidad Autonoma de Madrid in June 2004. He then entered an international PhD program at the Spanish National Research Council (CSIC) in collaboration with the Department of Material Science and Engineering at the Massachusetts Institute of Technology. Ramses is author of more than 30 scientific publications and 10 patents. He has been awarded with the Fulbright Fellowship and the Marie Curie IOF grant for his postdoctoral work in the lab of Prof. George Whitesides at Harvard University while he also served as a Teaching Fellow at the Harvard University Science Center. Dr. Martinez has also been an active mentor of undergrad and graduate students and is now teaching courses on Robotics, Material Science, and Engineering Design at Purdue University. His current research efforts focus in the development of new nanomanufacturing methods and soft and flexible robots.
