One aspect relates to a device including a hollow body, an inner volume and a surrounding volume. The inner volume includes an electronic component and the hollow body encloses the inner volume and includes a first component, a second component and an electrode. The first component is electrically conductive and the second component electrically insulates the electrode from the first component. The electrode includes a cermet, connects the inner volume to the surrounding volume in an electrically conductive manner, and includes a contact surface. The contact surface contacts eukaryotic tissue and has a maximum distance from the electronic component of less than 80 mm.
