Example embodiments relate to a system for monitoring biosignals and also to a patch and an apparatus which may include part of the system. The system may include a patch including a surface for attachment to a user, first sensors for sensing respective first biosignals of the user, and a transmitter for wirelessly transmitting first biosignal data representing the first biosignals of the user. The system may also include an apparatus for being worn or placed over the patch, the apparatus including second sensors at or near a lower surface thereof for sensing respective second biosignals of the user and providing second biosignal data representing the second biosignals. The apparatus may also include a receiver for wirelessly receiving the first biosignal data from the patch. The patch may include recesses or apertures for alignment with the second sensors when the apparatus is worn or placed over the patch.
