Micromirror Arrays for Smart Personal Environments

Energy saving potentials of micromirror arrays in active windows for smart personal environments (SPE) are studied. Such systems enable large area daylight guiding in buildings by application of electrostatically actuated micromirror arrays inside the noble gas or vacuum spacer between the panes of insulation glazings. The working principle in winter and summer scenarii is described. An alternative fabrication process for micromirror arrays, called transfer printing, is presented. For the first time we succeeded in fabricating micromirror arrays applying this novel transfer print.
