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.

Abstract: An apparatus includes a band configured to attach a physical activity measurement device to a human body, and electroactive material comprised in the band. The electroactive material is configured to change at least one of size and shape of the band in response to an electric input from the physical activity measurement device to the electroactive material.

Abstract: A wrist-worn physical activity measurement apparatus is disclosed. The apparatus includes a bracelet comprising a plurality of links, each link being formed at one side to comprise a part and at the opposite side a counterpart interlocking with a part of an adjacent link, and a flexible casing encasing the plurality of the links. The apparatus is attachable around a curvature of a wrist of a user such that the links and the adjacent links are pivotably lockable in relation to each other in order to wrap and lock around the wrist.
