Designed the Fraunhofer Institute for Reliability and Microintegration IZM in Berlin, the intruder detecting curtains are the newest way of stopping the menacing creating thieves in your neighborhood. The system contains a fine lattice of conductive threads interspersed among the polyester fibers. When the fabric is cut or penetrated, a built-in microcontroller springs into action, triggering an alarm that alerts authorities to the precise location of the break-in. IZM even went through extensive testing for it and put it through extreme weather and temperature conditions, ran it through washing machines, and even tested it inside a furnace. The system never failed.
