ABSTRACT
The paper compares the data obtained from a continuous wave Doppler radar sensor based on a commercially available microwave motion sensor KMY24 to an impedance cardiograph measured using a Cardiac Output Monitor (Medis Niccomo). Both sensors are used to analyze the mechanical activity of the heart. System parameters, signal content and robustness are discussed.
ABSTRACT
The paper describes an approach to monitor a person's ECG and activity continuously with functional clothing. A belt with integrated electronics has been developed and has proven long-term robustness of all electrical components. A low-power module measures the ECG signal as well as the acceleration (2-axis) and stores data continuously up to two days. A user test has been performed to evaluate the belt according to system performance at different daily-life activities like sleeping, walking and so on. System parameters are ECG-signal quality, system up-time, and ECG-signal coverage during a day.
