Abstract
The present invention relates to a solid-state variable capacitor, comprising a first capacitor plate (10), a second capacitor plate (12), extending substantially parallel to the first capacitor plate (10) and on a distance from said first capacitor plate, wherein at least the first capacitor plate (10) is structurally coupled to one side of a first layered solid-state battery wherein the layers (4-8) of said first solid-state battery (3) extend substantially parallel to the first capacitor plate (10) and wherein the first solid-state battery is susceptible to variations in the size in the direction perpendicular to the plane of its layers (4-8). This invention is based on the realization that the thickness of a solid-state battery (3) varies with conditions prevailing in the battery. The movable capacitor plate (10) causes a change of the capacitance value of the capacitor.
