The answer to better Wi-Fi security could lie on the surfaces of a wallpaper. A team of French researchers at Institut Polytechnique de Grenoble was able to develop a wallpaper that can allegedly block Wi-Fi signals. Working together with Centre Technique du Papier, the researchers claim that the wallpaper prevented Wi-Fi signals from being transmitted beyond the confines of an office or apartment. If you will observe the photo above of the said wallpaper, you will notice that it has a triangular snowflake-pattern.
