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.
