Researchers have designed a "fire alarm wallpaper" made of environmentally friendly, nonflammable materials—including some of the materials found in bone, teeth, and hormones—that can detect a fire, prevent the fire from spreading, and give off an alarm when a fire occurs. When exposed to heat, the wallpaper is transformed from an electrically insulating state into an electrically conductive one, causing it to automatically trigger an alarm that generates loud sounds and warning lights.
The researchers, led by Professor Ying-Jie Zhu at the Shanghai Institute of Ceramics, Chinese Academy of Sciences, have published a paper on the fire alarm wallpaper in a recent issue of ACS Nano.
