New Wallpaper Could Prove to be a Lifesaver
Scientists have devised a new method of making wallpaper. The new wallpaper changes state in the presence of fire, quickly responding and sounding an alarm.
One of the major problems with today’s wallpaper is that, due to being made from synthetic polymers and plant fibres, it is highly flammable. The new wallpaper, instead of literally feeding the flames, not only resists them, but alerts those nearby (and at an intermediate distance – it is not a quiet alarm) to the fire’s presence.
Head of the Chinese research team at the Shanghai Institute of Ceramics, Chinese Academy of Sciences, Professor Ying Jie-Zhu said that, "the fire-resistant wallpaper has a white colour, mechanical robustness, and high flexibility, it can be processed into various shapes, dyed with different colours, and printed with a commercial printer. Therefore, the fire alarm fire-resistant wallpaper has promising applications in high-safety interior decoration to save human lives and reduce the loss of property in a fire disaster."

The wallpaper is composed of nanofibers, a layer of graphene oxide treated with polydopamine in order to last longer, and an ink-based thermosensitive sensor. The sensor is located on the reverse side of the wallpaper so that it is protected and is mostly made of graphene oxide. At a normal temperature, graphene oxide does not conduct, however once temperatures exceed about 125°C the graphene oxide begins to conduct electricity. This completes a circuit containing a fire alarm. The response time is 2 seconds.
This new wallpaper could be a revolution. It is easy to mass produce and undeniably far better than anything on the market at the moment. The issue is the nanofibers, though with the current rate of technological advancement this will not remain an issue for long.

Pine cone facade: intelligent technologies inspired by nature
We always try to invent something new. Both intricate and technology-driven. Sometimes, however, all you need to do is to take a closer look at nature. Did you know that the outer shell of a pine cone closes when it gets wet and opens when it is dry and sunny?
