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 capacitively 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 onboard computation that integrates onboard 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 onboard 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.
