ABSTRACT:
A device to carry out a bioelectrical interaction with an individual by means of electrodes29, 29awhereby an on-demand verification of the integrity of the electrical contact of the electrodes is implemented. The device20comprises a control unit22arranged to determine an occurrence of the predefined event related to a quality of a measured signal. In case the predetermined event is detected, the control unit22actuates the testing means24. The testing means is arranged to generate the test signals, I1, 12and to apply them via a coupling circuit23, 23ato the electrodes. In case it is desired that cumulative information about the contact integrity is obtained, is it sufficient to apply a single test signal per electrode. In case it is required to determine which of the electrodes has lost its contact, a sequence of test signals is generated by the sequencer24b. The response signal from the electrodes29, 29ais forwarded to the input filter26, which is preferably also used for a normal signal analysis. The signal from the input filter26is directed via the input impedance25, 25ato the input amplifier28. The amplified response signal is forwarded to the signal processing means30which is arranged to analyze the response signal. Preferably, an amplitude analysis is done. The signal from the signal processing means30is supplied to the analog-to-digital converter (ADC)32after which a digital processing of the response signal is carried out by means of a further processing unit34. In case the further processing unit34determines that the integrity of the contact is below the allowable level, the lead-off indicator36is actuated.
