Удивительно, но банальная шишка вдохновила испытателей-учёных на создание прекрасной и очень полезной штуки.
4D printed ‘solar gate’ produces weather-responsive shades that open and close on their own
Researchers at the universities of Stuttgart and Freiburg have developed Solar Gate, a 4D printed, weather-responsive shade and facade system that closes and opens on its own. It doesn’t need electricity to run. It flips as soon as it detects changes in humidity and temperature. A reason behind it is that the researchers have succeeded in replicating the structure of cellulose fibers found in plant tissues using standard 3D printers. It is, however, dubbed 4D printed because these materials can alter their forms or movements after printing, in light of the tests.


The researchers use custom-engineered, biobased cellulose fibers for their 4D printed Solar Gate. They develop a computational fabrication method that controls the extrusion of this material. They then place the fibers into standard 3D printers. With this, they generate bilayered structures inspired by the scales of pine cones. The byproduct has the property called hygromorphism, which is an innate feature of a natural material like a pine cone to swell and shrink depending on the levels of humidity. This exact characteristic appears in the 4D printed Solar Gate.
Вот честно скажу - не отказался бы от таких занавесок. У меня почту 15 квадратных метро окон на южную сторону выходит. И летом приходится немного прикрывать.
The researchers have the 4D printed Solar Gate on the south-facing skylight of the building. These weather-responsive shades are responsible for the indoor climate regulation of the facility. During winter, the invention opens on its own to let the sunlight in for natural heating. In the summer, these shades autonomously close to reduce solar radiation. In a study the researchers published, they’ve evidently detailed how only the seasonal weather cycles power up the folding and unfolding of the 4D printed Solar Gate. Their research aims to prove two of many theories in the long run. Accessible and cost-effective technologies, such as additive manufacturing, are possible. In another case, cellulose can also be an abundant and renewable material for architectural solutions.
