An electrical implant or implant system includes an energy supply unit or is connected to an energy supply unit and includes at least one fixing device for permanently fixing the electrical implant or implant system to bodily tissue, or is connected to the fixing device. At least two implant components are releasably mechanically connected to one another. A first of the implant components includes at least parts of the fixing device. A second of the implant components includes an electromechanical component which, as a result of current drain or current feed, can swell in such a way that it causes a swelling at an outer contour of the electromechanical component at least at one point. The electromechanical component is disposed in such a way that a swelling of the electromechanical component results in a separation of the mechanical connection between the first and second implant components.
