The primary goal of this work is to improve the recording, analysis, and interpretation of biopotentials to assess human performance and medical status by developing a small foot-print flexible hybrid electronics wearable ECG monitor that will evaluate the advantages of capacitive coupled electrodes. The ability to record and analyze high-quality signals can only be addressed by meeting the technical challenges of low-level signal detection, amplification, and on-board computation that integrates on-board and host supported systems. Building on prior NBMC funded projects, the improved subsystems include smaller higher capacitance electrodes, improved high-gain/low-noise front-end signal amplification and processing, expanded computational power, increased on-board memory, and on-board operational, signal analysis, and alarm generating software. These subsystems are being electrically and mechanically integrated on an improved redesigned substrate along with noise shielding and improved electrode/body connection for optimum signal detection. The flexible high capacitance electrodes, featuring a high dielectric nanolaminate deposited by an atomic layer deposition system, are being evaluated for signal pick-up, reliability, and wearability. The front-end analog amplification and filtration circuitry have been designed to utilize readily available components and to minimize the component count; thereby, reducing monitor size and ensuring future manufacturability. This progress report will present results from a PCB level prototype that will establish the operating parameters for the final design and implementation of a fully integrated flexible hybrid electronics monitor. Support: NBMC 19-17 funded by the US Air Force Research Laboratory and the New York State Empire Development Corporation.
