Disclosed is a sensor for detecting myoelectric signals, comprising a cylindrical base (1) on which at least one electrode array (2a, 2b, 2c) is disposed that is composed of electrodes which are evenly distributed along the circumference and lie on a peripheral circle, said electrode array (2a, 2b, 2c) making it possible to detect action currents of a muscle, particularly a sphincter. The inventive sensor is characterized in that one electrode array (2a, 2b, 2c) encompasses at least twelve electrodes while at least two identically configured electrode arrays (2a, 2b, 2c) are provided which are located immediately one behind another at a short distance from each other. |
