This talk will explore the new realm of using threads as an ultimate platform for flexible and stretchable bioelectronics. Threads offer unique advantages of universal availability, low cost, material diversity and simple textile-based processing. Interestingly, threads also provide an ideal platform for passive microfluidic sampling and delivery of analytes. In this talk, I will report reel-to-reel fabrication of functional smart threads for variety of sensing and electronics application. I will report on nanomaterial-infused smart threads for sensing strain and temperature. Nano-infused threads will be presented for sensing pH, glucose, lactate, ammonium and other chemical and biological biomarkers directly in biological fluids such as sweat or wound exudate. Beyond sensing and microfluidics, I will present our recent work on making super-thin transistors and electronics directly on threads. This new toolkit of highly flexible thread-based microfluidics, sensors, transistors and electronics makes it possible to realize smart surgical sutures and flexible smart bandages for chronic wounds. Our recent work on using threads for closed loop spatiotemporal dosage controlled drug delivery will also be presented. If there is time, I will present some related research activities on ingestible devices for studying the gut microbiome, and on flexible microneedles for transdermal drug delivery.Professor, Electrical and Computer Engineering, Tufts University
