The invention relates to a wearable device arranged for enabling a bioelectrical interaction with an individual when being brought into contact with the individual's skin I, said device comprising electrodes 2 arranged to carry out said interaction by means of a first electrical signal, said electrodes comprise motion artifact detection means 4. The electrode assembly 1 comprises electrode 2 arranged to carry out a bioelectrical interaction with the individual by means of measuring an electrical signal on the body of the individual I and/or applying an electrical signal to the body of the individual. In order to enable said bioelectrical interaction the electrode 2 is provided with an electrical cable 2 a. According to the invention, the electrode 2 is arranged with a pr 4. The pressure sensor 4 is arranged to measure a normal force component of an external force applied to the electrode due to movement of the individual. Preferably the pressure sensor 4 is a force/pressure sensitive resistor or a capacitive pressure sensor. The pressure sensor is arranged to produce an electrical signal, referred to as the second signal, the magnitude of the second signal being proportional to the pressure load. The pressure sensor 4 is arranged with cables 4 a, 4 b for purposes of signal proce
