Abstract
There is provided a wearable device for measuring cardiac activity of a user, the wearable device comprising: an optical cardiac activity sensor unit configured to be placed in contact with a measurement area and to enable cardiac activity measurement of the user to obtain a cardiac activity signal; a plurality of electrodes configured to enable bioimpedance measurement on the measurement area to obtain a bioimpedance signal; a detector unit for detecting changes in the bioimpedance signal; and a reducer unit for reducing a motion artefact effect on the cardiac activity signal based on the detected changes in the bioimpedance signal.
