Skins with attitude: Hygroskin and breathing Thermobimetals

Skins with attitude: Hygroskin and breathing Thermobimetals

Isn’t it so? A skin with an attitude, a breathing skin! This reminds me of a previous post  where pieces of wood danced with heat displaying beautiful flower shapes. NI.TIN.OL a composite of nickel, titanium alloy, is what makes this happen, it is the similarity with pine cones when its season is passing by, as you will find in the video.

The future of materials at its best here with the simple display of wood composite skin with the resemblance of nature. How close are we for this to surpass a prototype and be actually used on construction? Or even an object that can act as an air purifier at home? My investigation and colleague discussions have been turned around solutions composed of nitinol and polymers as agents that provide personality to materials, that make them react to the environment. How long can this action persist if climate is changing as fast as technology evolves?

This new pavilion called Meteorosensitive Architectural Skin, designed at the Institute of Computational Design in Denmark, is a taste of the future and as a skin, acts also as a light source; still a prototype but seems like it will be very much accepted as an option to develop new possibilities of skins that act under natural effects…but what if this new material as it reacts to the environment not only dynamically because of temperature, but also it can absorb toxicity in the environment? Can it be done? Does it already exist?

Doris Kim Sung, a Biologist who then became a Architect, invented a similar system within this topic, first: a breathing skin made of thermobimetals and the inverted physique where the skin elevated and curls as a sort of eyelash, then a skin that acts a the breathing system of a grasshopper, using as a skin that allows air to flow through and block it where needed as a substitute of windows.  The other system she’s designing, is a layer inside the glass panel that curls and uncurls inside according to the need of sun or shadow.

These new smart materials are supposed to not fail because is a natural reaction of this material, but how long can this material persist? Is the constant reaction ends up making it loose its strength?
