An implementation for an electret in a capacitive MEMS element including a pressure-sensitive diaphragm, which is produce-able using standard methods of semiconductor technology for easy integration into the manufacturing process of MEMS semiconductor elements. Such MEMS elements include at least one pressure-sensitive diaphragm including at least one deflectable diaphragm electrode of a capacitor system for signal detection and one fixed non-pressure-sensitive counter-element including at least one counter-electrode of this capacitor system, at least one electrode of the capacitor system being provided with an electrically charged electret, so that there is a potential difference between the two electrodes of the capacitor system. The electret includes at least two adjacent layers made from different dielectric materials, electrical charges being stored on their boundary surface.
