A system for monitoring a physiological condition of an individual. The system (1) comprises sensing means (3) arranged to pick up a first signal (M) in a first mode of the system, said first signal being representative of the physiological condition and to forward the first signal to a signal processing unit (33). The system comprises an actuatable control unit (2) positioned remote from the signal processing unit, the control unit (2) being suitable to generate a second signal (T) arranged to be superimposed on the first signal (M). The signal processing unit (33, 37) is arranged to decode the second signal and to make the system enter into a second mode upon receipt of the second signal (T).

The system (1) according to the invention is arranged to support an automatic informing of callers (S1, S2, . . . , SN) upon an event of an interrupt in a telecommunication line engaged with a receiving station (4) according to a telecommunication protocol. In order to carry out said automatic informing the receiving station (4) is adapted with a computer program (6,8,10,12,14) arranged to transmit a prerecorded message to all engaged parties upon an event of the interrupt. The computer program is further arranged to carry out background interaction with a caller who is put on hold, so that the caller is not left behind unattended.

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 the 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 2a. According to the invention, the electrode 2 is arranged with a pressure sensor 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 4a, 4b for purposes of signal processing.
