Researchers in Grenoble have had an original idea to prevent your Wi-Fi network from being hacked, you can use wallpaper that block your Wi-Fi signal from leaving the apartment and thus keeping it safe from hackers. Other uses may be found in this technology, such as the protection of sensitive persons from electromagnetism.
Recently its creators presented a prototype of this “revolutionary wallpaper” to the press. It protects data from a network connected via Wi-Fi from any intrusion, since it has the ability to filter out
electromagnetic waves of a wireless LAN, yet without disturbing the radio frequency of signals of cell phones.
If you put wallpaper on the walls around an office or apartment, your Wi-Fi works well but it can not be hacked,” explained Pierre Lemaitre-Auger, a researcher at the Polytechnic Institute Grenoble Institute of Technology and a developer of the product.
The design was done in collaboration with the Centre Technique du Papier, by a team comprising a total of 4 persons. The finished product is covered with geometrical tracings with conductive ink (ink containing silver particles), and if you do not like the way it looks, do not worry: you can cover it with another wallpaper of your choice, without altering it’s filtering properties.
In addition, the harmfulness of electromagnetic waves is still under debate: “Many people are interested in the problems of electrosensitivity, and believe the waves could be dangerous to one’s health,” said Pierre Lemaitre-Auger. The product can also provide people who want the opportunity to protect themselves from electromagnetic waves as a precaution in their apartment.” The scientist added that its use in this context may be especially helpful in other setting such as in hospitals – where equipment may be sensitive to, or emit electromagnetic radiation, theaters – to block cell phone and pager noise.
And, if there is a problem of electromagnetic porosity, the technology could be also be used in flooring, ceilings and windows, as pointed out by Guy Eymin Petot Tourtollet, CTP.
The price of the wallpaper would be “reasonable” and “equivalent to that of a classic wallpaper mid-range”, the paper is expected to be ready in early 2013, as projected by the Finnish company, Ahlstrom, who has the license for the exclusive manufactures of the wallpaper.
