The BaTiO3 and other ceramics have fractal configuration nature based on three different phenomena. First, ceramic grains have fractal shape looking as a contour in cross section or as a surface. Second, there is the so-called “negative space” made of pores and inter-granular space. Third, there is a Brownian process of fractal motions inside the material during and after sintering in the form of micro-particles flow: ions, atoms and electrons. Here we met an exciting task of the Coble model, with already extended and generalized geometries. These triple factors make the microelectronic environment of very peculiar electro-static/dynamic combination. The stress is here set on inter-granular micro-capacity and super micro-capacitors in function of higher energy harvesting and energy storage. An attention is paid to components affecting overall impedances distribution. Con¬struc¬tive fractal theory allows recognizing micro-capacitors with fractal electrodes. The method is based on the iterative process of interpolation which is compatible with the model of grains itself. Inter-granular permeability is taken as a function of temperature as fundamental thermodynamic parameter.
