To keep the body warm and dry during winter sports, high-performance clothing is a must. The demands on these textiles are high, as a person sweats up to one liter per hour on his upper body alone when skiing. A new technology, co-developed by a team of Empa scientists, helps athletes sweating by actively transporting moisture away from the body and to the outside. This is possible because ultra-thin layers of gold in the fabric are electrified.
Man is a warm-blooded animal. If it gets too hot for him, he can tune down his body temperature. This feat is achieved by an evolutionarily refined "AC system"...30.01.2018 | Read more
Wearable sensors are revolutionizing the tech-world, capable of tracking processes in the body, such as heart rates. They're even becoming fashionable, with many of them sporting sleek, stylish designs. But wearable sensors also can have applications in detecting threats that are external to the body. Researchers now report in ACS Sensors a first-of-its kind device that can do just that. And to stay fashionable, they've designed it as a ring.
According to a global analyst firm called CCS Insight, wearable electronics will be a $34 billion industry by 2020. Wearable chemical sensors currently in...12.10.2017 | Read more

Coating to make soap pour cleanly out of plastic bottles, reduce waste and frustration
It's one of life's little annoyances: that last bit of shampoo that won't quite pour out of the bottle. Or the last bit of hand soap, or dish soap, or laundry...27.06.2016 | Read more
An ultra-high-speed CMOS image sensor that offers 10 million frames per second with ISO16,000 photosensitivity has been developed by researchers at Tohoku University.

Crackpot idea or recipe for success? This is a question entrepreneurs often face. Is it worth converting the production process to a new, ecologically better material? Empa has developed an analysis method that enables companies to simulate possible scenarios – and therefore avoid bad investments. Here’s an example: Nanofibers made of carrot waste from the production of carrot juice, which can be used to reinforce synthetic parts.
All over the world, research is being conducted into biodegradable and recyclable synthetics. However, fiber-reinforced components remain problematic – if...06.08.2015 | Read more
Whether it's fallen concrete pylons caused by corroded tension wires, a new motor due to damaged pistons or defective sheet steel, even the tiniest cracks or smallest traces of corrosion can have serious consequences, especially in safety-critical environments.
With magnetic stray flux inspections, these flaws can be quickly visualized without destroying or contaminating the material.28.04.2015 | Read more
Canadian researchers are developing less expensive ways to embed glass fibers in a stretchy elastomer that could one day be used in slip-resistant winter footwear
Winter storms dumped records amounts of snow on the East Coast and other regions of the country this February, leaving treacherous, icy sidewalks and roads in...18.03.2015 | Read more
Groundbreaking new clean technology aims to bring water independence to those in need
Today sees the launch of a campaign to bring an end to the world water crisis by providing sustainable, pure drinking water to up to a billion people without a...02.12.2014 | Read more
Soma is the first designer water filter in the world made from natural resources. The bioplastic used for this filter is Bio-Flex®, a material developed by Fraunhofer UMSICHT in cooperation with FKuR.
It all started with an “oops.” When Mike Del Ponte, founder of Soma, hosted a dinner party, he was unwilling to place a cheap plastic water filter on his...22.10.2014 | Read more
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...
The well-known representation of chemical elements is just one example of how objects can be arranged and classified
The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to...
Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
