Abstract:
1. A device for stimulating living tissue cells or nerves, comprising: stimulating electrodes configured to be in contact with living nerve cells or tissue and configured to stimulate the living nerve cells or tissue by individual or repeated stimulating pulses of the stimulating electrodes; a pulse-generator and a current/voltage source arranged to provide the individual or repeated stimulating pulses to the stimulating electrodes, wherein the stimulating electrodes have an electric voltage and an electric charge in response to the at least one pulse; a coulombmeter and/or a voltmeter which is connected to the stimulating electrodes and which determines a voltage on or an imbalance of electric charges on the stimulating electrodes; and an electrical circuit which performs feedback control to control the electric voltage or the electric charge remaining on the stimulating electrodes as a function of the electric voltage between the stimulating electrodes and reduces or equalizes imbalances of electric charges on the stimulating electrodes; and wherein the electrical circuit includes a charge-injector that is connected to the current/voltage source and to the coulombmeter and/or voltmeter and to at least one of the stimulating electrodes, wherein the charge-injector generates a positive or negative electric current of defined duration and intensity based on the determination of the coulombmeter and/or voltmeter and applies the positive or negative electric current to the stimulating electrode, as a result of which imbalances of electric charges on the stimulating electrodes are reduced or equalized.
