Abstract:
Methods and systems to improve a multilayer ceramic capacitor using additive manufacturing are disclosed. Layers of a capacitor may be modified from its traditional planar shape to a wavy structure. The wavy shape increases surface area within a fixed volume of the capacitor, thus increasing capacitance, and may comprise smooth and repetitive oscillations without the presence of voltage-degrading sharp corners. In addition, the ends of each conductive layer do not have sharp edges, such as comprising of a round corner. The one-dimensional wave pattern may run parallel to the width of the capacitor, or it may align in parallel to the length of the capacitor. In some embodiments, the wave pattern may be parallel to both the width and the length—in two dimensions—such that it forms an egg-crate shape. Further, the wavy structures may comprise of secondary or tertiary wavy structures to further increase surface area.
