Abstract
This study proposes a system for constant monitoring of ECG and respiration signals using a wearable. The proposed system uses capacitively-coupled electrodes for the measuring of the ECG-signal and a resistive strain sensor for the measuring of the respiration signal. The system applies the strain sensor to the abdomen of a patient, and integrates the electrodes with the rest of the components into clothing to maximize comfort. A battery life of at least 12 hours before changing the battery to recharge is estimated. Options for changing the system or its components to favour certain applications are discussed. A graphical user interface is developed which includes a login screen based on the SHA-256 hashing algorithm, a patient tab that visualizes stress and other important features, and a physician tab that also includes the raw data and options for contacting or adding a patient. The graphical user interface uses pre-measured data stored on a Microsoft Azure server.
