The present paper introduces a patient-friendly embedded electrographic (ECG) amplifier. In contrast to the standard ECG amplifier, the presented system uses only two electrodes to insure unobtrusiveness and compact design. The abandoned third reference electrode and required low power consumption introduce problems in ECG signal preamplification and(More)
The present study concerns the nondisturbing assessment of cardiovascular oscillations of the carotid artery using a novel skin curvature sensor on the neck. The mechanical oscillations of the skin reflect changes of the artery radius and thus relevant physiological data such as cardiac and respiratory activities, their mutual dependencies, and even changes(More)
