Organic mixed ionic electronic conductors for electrochemical devices
Abstract/Contents
- Abstract
- The development of wearable devices for continuous health monitoring of biomarkers requires materials that are mechanically compliant, biocompatible, and are sensitive to biochemical molecules. One class of materials that show promise are Organic Mixed Ionic Electronic Conductors (OMIECs), commonly semiconducting polymers, which are redox-active and can simultaneously conduct ions and electrons. Electronic charges accumulated on the conjugated polymer backbone result in secondary property changes in electrochemical potential and electronic conductivity, allowing OMIECs to be implemented in a variety of devices such as chemical sensors, organic electrochemical transistors, and energy storage electrodes. Additionally, the mechanical flexibility and biocompatibility of these polymers enable conformable and seamless integration with biological interfaces, enabling bio-interfacing devices for continuous health monitoring. My PhD research investigates how OMIECs can be designed, characterized, and implemented in 1) polymer-based batteries for energy storage, 2) electrochemical sensors for the detection of biological analytes, 3) organic electrochemical transistors that amplify biosensing signals, and 4) tunable antennas for wireless signal transmission in microwave frequencies compatible with consumer electronics. Leveraging fundamental materials characterization to drive the understanding of device physics, these OMIEC-based technologies are integrated into a fully self-powered and wireless glucose sensor.
