A movable platform structure including a base structure, a platform and an articulated system which connects the platform to the base structure, wherein the platform is movable between a raised position which is horizontally adjacent to the base structure and a lowered position which is horizontally far from the base structure. The method further involves the steps of storing the electrical signal, and playing back the electrical signal by activating the electrode during the absence of the preselected event. In some embodiments, the configurable circuits, UDS circuits, and tracer buffer are on a single IC die. The invention has many applications for photoelectric conversion devices, batteries, capacitors, electrochromic displays, chemical sensors, biological sensors, light emitting diodes, electrodes, semiconductors, separation membranes, selective adsorbents, adsorbents for HPLC, catalysts, implants, nanoparticles, antiadhesives, and anticorrosion coatings, for example. This crystal growth occurs with the diffusion of the nickel element.
