Wearable sensing device and sensor unit for acquiring one or more physiological signals of a subject

A wearable sensor unit for acquiring one or more physiological signals of a subject, comprising:

• a housing;
• a connection receptacle;
• and
• electronic circuitry configured for acquiring and/or processing one or more physiological signals received via the connection receptacle;
• and
• wherein the wearable sensor unit is further configured such that
• the housing comprises a surface to be fixedly attachable to a patch unit;
• the connection receptacle is arranged for receiving a connection plug
• and signals from said patch unit;
• and
• the electronic circuitry is arranged for acquiring one or more physiological signals received via the connection receptacle and originating from a plurality of electrodes for sensing the one or more physiological signals in said patch unit.

A kit of individual parts comprising:

• a sensor unit, including a housing, a connection receptacle and electronic circuitry configured for acquiring one or more physiological signals received via the connection receptacle;
• a patch unit, including a connection plug connected via conductive tracks to a plurality of electrodes configured for sensing the one or more physiological signals;
• and wherein the connection plug is configured for being connectable with the connection receptacle such that the one or more physiological signals sensed by the electrodes are transmitted to the electronic circuitry of the sensor unit;
• and
• the patch unit comprises at least one top layer and at least one bottom layer, each including an adhesive material, such that the at least one top layer is configured to be attachable to a surface of the housing and the at least one bottom layer is configured to be attachable to the skin of the subject.
