Hanging by a thread: sensors, microfluidics, electronics and drug delivery

March 29, 2019
2:00 PM - 3:00 PM

Speaker: Prof. Sameer Sonkusale, Tufts University

Abstract:
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. In this talk, I will report reel-to-reel fabrication to make functional smart threads for variety of sensing and electronics application. For example I will report on nanomaterial-infused smart threads for strain and temperature sensing. Threads will be presented for sensing pH, glucose, and other chemical biomarkers. Interestingly, threads also provide an ideal platform for passive microfluidic sampling and delivery of analytes. I will show our recent work on using this toolkit of thread-based microfluidics, sensors and electronics for application as 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 research activities on chemical sensor array aka artificial nose, and on CMOS image sensors to support such sensing functions.
