Simultaneous physiological measurements with five devices at different cognitive and physical loads

This open database contains physiological measurements from 13 adult and healthy subjects during a standardized experimental setup. The physiology was examined with five different devices (NeXus-10 MKII, eMotion Faros 360°, SOMNOtouch NIBP, Hexoskin Hx1, Polar RS800 Multi), which, in contrast to other studies, were recorded simultaneously. The experiment included a five minute baseline measurement, five minute walking on the treadmill, a five minute cognitive audio test, and a five minute uphill walking on the treadmill. Measurements included electrocardiography (ECG), photoplethysmography, accelerometry, oxygen saturation, respiration, heart rate, heart rate variability, and RR intervals sampled between 1 Hz and 8000 Hz. The dataset was originally generated during an investigation of functionality, accuracy, and usability of several ECG-measurement devices. This resource included the complete raw data files (EDF and HRM) and merged data with a manual expert annotation of heart beats and annotation files with information about the beginning of each experimental phase.
