(Invited) seamless Integration of Electronics, Electrochemistry, Microfluidics, and Materials for Next Generation Tissue-Integrated Sensors and Energy Devices

Abstract

Recent advances in materials, mechanics, and device architectures form the foundations for rapidly emerging classes of sensors and energy devices with mechanical characteristics that allow for conformal interfaces with the soft, curvilinear surfaces of the human body. While the field of tissue-integrated biophysical sensors exhibits commendable progress in capturing clinical quality thermal, kinematic, and electrophysiological information, the advancement of complementary biochemical sensors severely lags due to unique challenges associated with seamless integration of delicate biochemical receptors, transducing components, and suitable packaging materials. Similarly, the vast majority of demonstrated tissue-mounted energy storage and energy harvesting systems unfortunately rely on toxic components that substantially diminish their attractiveness in bio-related applications. In this talk, I will discuss non-traditional approaches to address some of these grand challenges. Specifically, I will discuss three technologies that my lab is developing -1) wearable, self-powered sweat sensors for non-invasive health monitoring 2) wireless, implantable, battery-free sensors and optoelectronics for neuroscience research, and 3) fully resorbable batteries for broad applications in medicine and consumer electronics.
