Get rid of sweat at the push of a button

19.11.2018

The Swiss sportswear manufacturer KJUS presented the world's first ski jacket with an integrated electronic user-controlled membrane on November 15. Thanks to the HYDRO_BOT technology developed together with Empa, the ski jacket actively pumps out sweat from inside the jacket to keep skiers dry and warm.

Efficient clothing is needed to keep the body warm and dry during winter sports. The demands placed on such textiles are high, as people sweat up to one liter per hour on their upper body alone when skiing.


During winter sports, the body produces a lot of moisture. Nevertheless, new functional clothing ensures a pleasantly warm and dry microclimate.

KJUS

The new ski jacket of the Swiss premium sportswear brand KJUS removes sweat from the inner clothing and transports it out of the jacket. This eliminates the problem of cooling down after skiing, which is otherwise caused by the moisture trapped in the inner clothing. This ensures that skiers spend minimal energy to stay warm and, thus, have more energy for their sport.

This is made possible by the innovative HYDRO_BOT technology, in which two functional membranes are integrated in the back zone of the jacket, where one usually sweats the most. The technology consists of three layers: a membrane of billions of pores per square meter surrounded by an electrically conductive fabric.

By means of a small electrical impulse, the pores turn into micro-pumps that actively conduct moisture away from the body quickly and efficiently. The jacket is extremely easy to switch on and off using the integrated control unit or the iPhone & Android app.

Developed and patented by the Swiss company Osmotex, HYDRO_BOT is a revolution for the clothing industry and the first significant innovation since the introduction of waterproof and breathable membranes 40 years ago.

More than ten years of research and development in collaboration with Empa and Swiss textile manufacturer Schoeller have formed the basis for this innovation.

The new membrane technology solves one of the biggest challenges in the ski and sportswear sector: breathability and the problems that inevitably occur when a skier sweats at sub-zero temperatures while wearing warm, waterproof clothing.

Ski jackets with normal membranes cannot transport moisture away from the body quickly enough, especially in colder outdoor temperatures, because the breathability of normal membranes quickly diminishes.

The new jacket is up to ten times more efficient than normal membrane jackets and is not affected by freezing temperatures. It is the first garment that can keep up with human perspiration rates in terms of breathability.

Im Focus: Better thermal conductivity by adjusting the arrangement of atoms

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.

In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Im Focus: First-ever visualizations of electrical gating effects on electronic structure

Scientists have visualised the electronic structure in a microelectronic device for the first time, opening up opportunities for finely-tuned high performance electronic devices.

Physicists from the University of Warwick and the University of Washington have developed a technique to measure the energy and momentum of electrons in...

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
