the invention relates to a micromechanical sensor having at least two spring - mass damper oscillators . the micromechanical sensor has a first spring - mass - damper oscillating system with a first resonant frequency and a second spring - mass - damper oscillating system with a second resonant frequency which is lower than the first resonant frequency . the invention also relates to a method for detection and / or measurement of oscillations by means of a sensor such as this , and to a method for production of a micromechanical sensor such as this . the first and the second spring - mass - damper oscillating systems have electrodes which oscillate in a measurement direction about electrode rest positions with electrode deflections which are equal to or proportional to deflections of the spring - mass - damper oscillators . the systems are coupled to one another by means of at least one electrostatic field , which acts on the electrodes , forming at least one capacitance with the capacitance being governed by at least one electrode area and by at least one electrode separation and / or an electrode coverage .
