![]() ![]() Apart from severely restricting the independence and mobility 3, 4, irritation by the electrodes might lead to undue distress and even increase the symptom burden 5. All current devices have the common disadvantage that they need to be in permanent contact with the person. While the ECG makes use of the electrical stimulation that triggers each heartbeat 1, the PPG measures the changing absorbance caused by the blood flow 2 and the PCG measures the acoustic waves that result from the mechanical activity of the heart. State-of-the-art technologies for vital sign monitoring include the electrocardiograph (ECG), the photoplethoysmograph (PPG), or the phonocardiograph (PCG). Vital signs, such as heart rate and respiratory rate, are key parameters when assessing the physical condition of a person. The presented dataset contains reference-labeled ECG signals and can therefore easily be used to either test algorithms for monitoring the heart rate, but also to gain insights about characteristic effects of radar-based vital sign monitoring. Overall, around 223 minutes of data were acquired at scenarios such as breath-holding, post-exercise measurements, and while speaking. 11 test subjects were measured in different defined scenarios and at several measurement positions such as at the carotid, the back, and several frontal positions on the thorax. This dataset consists of synchronised data which are acquired using a Six-Port-based radar system operating at 24 GHz, a digital stethoscope, an ECG, and a respiration sensor. Potential applications include the employment in a hospital environment but also in home care or passenger vehicles. This approach is able to tackle crucial disadvantages of state-of-the-art monitoring devices such as the need for permanent wiring and skin contact. Radar systems allow for contactless measurements of vital signs such as heart sounds, the pulse signal, and respiration. ![]()
