Everybody knows about origami, this impressive skill of folding a piece of paper, generally resulting in amazingly complex figures. You won’t be surprised to know that nature masters this art, and has been mastering it for probably much longer than humans. The earwig’s wing is the perfect illustration. This is where art, biology and engineering meet. Researchers from the ETH Zürich and the Purdue University combined their skills to develop a bio-inspired spring origami, drawing their inspiration from the unusual folding system of the earwig’s wing. The work showed that the insect’s wing doesn’t respect one of the mathematical aspect of origamis (the angular sum should be equal to 360˚). This allows them to have an area during the flight 10 to 18 times larger than when the wings are retracted, and they remain open by a bistable locking mechanism during flight and self-fold rapidly with no muscular actuation. Weird right? This arises from the material from which the joints on the wing are made: an elastic biopolymer called resilin which works as an extensional and rotational springs so that the wings can fold in an elastic way. Using the results obtained and a 3D printer, the researchers succeeded to make a prototype able to act juste like the earwig’s wing.
Just for once, we have created a ID card on a material that will be marketed in 2024, under the reference M0781. An aluminum whose production no longer generates greenhouse gases, but only oxygen. Of course, matériO is generally abstraining from activating sheets on a material until it is not available; because why make you dream about incredible things which you cannot use for your projects? But two reasons induced us to infringe this rule; first of all the fact that we are probably facing a real revolution in aluminium production, comparable to what happened in the 1950s' with the emergence of float glass production. And also because it can be interesting to integrate this innovation for your long-term projects.So, keep posted ...
It was last Thursday, during the Materials&Light fair. Our monthly frühstück (Presentation of the latest matériO' novelties) took place exceptionally at « Le Carreau du Temple » : There was around hundred people, pretzels for each participant and above all forty extraordinary materials. You can see the pictures of this event on our Facebook page, and you will find all the materials we talked about by simply typing "frühstück21 » in the search bar of our website, and let’s go ! These wonderful materials are yours for your next projects.
Wastewater, sewage plant, sewage sludge, does that mean anything to you? I mean, are you okay to talk about it?
In general, we only meet these elements because of their smell that is mostly consider disgusting, at the random crossing of a station on our way, or because the school had the wonderful idea of making a class outing that makes all the children laugh, in the West at least.
Currently, much of the wastewater is discharged into the nature without being collected or treated, however we are discovering that it can be a wonderful source of raw materials, energy and simply clean water.
Nutrients such as phosphorus, biogas production, electricity... So many essential elements - or almost - that can be produced in wastewater treatment plants !
In the Netherlands the "Energie- en Grondstoffenfabriek", literally "Energy and raw materials factory network", was created by the water authorities to work collectively on this energy production and raw material extraction, And they can boast of being the first to succeed in extracting the cellulose contained in toilet paper to recycle it! AH, here we are, finally getting into the matter. To celebrate this small step forward, they invited the studio of the designer Nienke Hoogvliet to create a series of objects that show how this recycled material can be integrated into our homes: thus was born a collection named "Watterschatten", or "Water Treasures", including a table, lights and bowls, which you can see on the pictures.
This kind of things regain us a bit of prestige, all those taboo things coming from us we have to deal with every day, it finally look useful! Striking news that we are part of this ecosystem isn't it!
