摘要：
The present invention relates to a wearable device for obtaining signals from a subject for use in the monitoring of pulse-related information of the subject. To enable the use of such a device in the monitoring of pulse-related information of the subject, which provides for unobtrusive, reproducible, easy to use, and simple measurements, the device comprises a device body (20), a PPG signal sensing unit (21) for acquiring a first photoplethysmography, PPG, signal from a first body location of the subjects body, and an imaging unit (22) for acquiring a sequence of images from a second body location of the subjects body different from the first body location, said sequence of images being configured for deriving a second PPG signal for the second body location of the subjects body. Said PPG signal sensing unit and said imaging unit are mounted in or at the device body and are configured to simultaneously acquire the first PPG signal and the sequence of images.
