‘Metapaper’ blocks Wi-Fi signals.
French researchers have developed a wallpaper able to block Wi-Fi signals, while still allowing FM radio waves and emergency frequencies to pass through. Known as metapaper, it is able to filter out 99% of all waves coming from the outside.
Possible uses could include creating quiet spaces inside movie theaters or hospitals, or for the ultra paranoid it could be used to stop the neighbors stealing your Wi-Fi or hacking into a wireless home network.
The snowflake patterned wallpaper can be covered with traditional wallpaper. The makers are pushing it as a ‘healthy alternative’, citing studies showing that overexposure to electromagnetic waves could cause adverse health affects.
