The sensor unit and the patch can be connected to one another via a connector arranged on the patch in such a way that an electrical connection is produced and the sensor unit is held on the body via the patch. The sensor unit has a plurality of contact elements for electrically contacting the connector and/or the patch. According to the invention, at least two contact elements of the sensor element are conductively connected to one another via a conductor track of the patch by connecting the patch to the sensor unit. ## Claims ### Claim 1 A system for detecting biosignals having a sensor unit and a patch that can be attached to a body and has electrodes and conductor tracks, wherein the sensor unit and the patch are connectable to one another via a connector arranged at the patch such that an electrical connection is established and the sensor unit is held at the body via the patch, wherein the sensor unit has a plurality of contact elements for an electrical contact of the connector and/or of the patch, wherein at least two contact elements of the sensor unit are conductively connected to one another via a conductor track of the patch by the connection of the patch to the sensor unit. ### Claim 2 (depends on 1) The system in accordance with claim 1, wherein the sensor unit recognizes that it has been connected to a patch and automatically switches itself on as a response. ### Claim 3 (depends on 2) The system in accordance with claim 2, wherein the patch and the sensor unit are set up such that a circuit of the sensor unit is closed by the connection of the patch to the sensor unit. ### Claim 4 (depends on 2) The system in accordance with claim 2, wherein a recording of signals starts automatically when the sensor unit recognizes that it has been connected to a patch;
