Some golf carts and lawnmowers already use airless tires and at least one major tire company produces a non-pneumatic automotive tire, but we still have long way to go before they are on every vehicle that comes off the assembly line. Finding a design that balances puncture-free strength with the elasticity needed for a comfortable, shock-free ride like conventional pneumatic tires is the key.
To address some of the issues, University of Illinois researchers focused on one component of the tire--the shear layer, which is just beneath the tread.30.01.2020 | Read more
Taking a child along in a wheelchair is not an easy task for people with walking disabilities. Within the framework of several student projects, young engineers at Technische Universität Kaiserslautern (TUK) have dealt with this topic. In the meantime, the team has developed a prototype in which a child seat can simply be attached to a wheelchair using a rail system. The seat can be adjusted to any position with only very little effort. At the medical technology trade fair “Medica” from 18 to 21 November in Düsseldorf, the team will present the technology at the research stand Rhineland Palatinate (Hall 7a, Stand B06).
The rail system, which curves around the wheelchair, resembles a bicycle frame. A child seat can be attached to it in a few simple steps. "The seat can be...06.11.2019 | Read more
A therapeutic shoe engineered to improve stroke recovery is proving successful and expected to hit the market by the end of the year. Clinical trials have been completed on the U.S. patented and licensed iStride Device, formerly the Gait Enhancing Mobile Shoe (GEMS), with results just published in the Journal of NeuroEngineering and Rehabilitation.
Stroke sufferers experience muscle weakness or partial paralysis on one side of the body, which greatly impacts how they walk, known as gait. Gait asymmetry is...18.09.2019 | Read more
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

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

The Belle II experiment has been collecting data from physical measurements for about one year. After several years of rebuilding work, both the SuperKEKB electron–positron accelerator and the Belle II detector have been improved compared with their predecessors in order to achieve a 40-fold higher data rate.
Scientists at 12 institutes in Germany are involved in constructing and operating the detector, developing evaluation algorithms, and analyzing the data.
Electrolytes play a key role in many areas: They are crucial for the storage of energy in our body as well as in batteries. In order to release energy, ions - charged atoms - must move in a liquid such as water. Until now the precise mechanism by which they move through the atoms and molecules of the electrolyte has, however, remained largely unknown. Scientists at the Max Planck Institute for Polymer Research have now shown that the electrical resistance of an electrolyte, which is determined by the motion of ions, can be traced back to microscopic vibrations of these dissolved ions.
In chemistry, common table salt is also known as sodium chloride. If this salt is dissolved in water, sodium and chloride atoms dissolve as positively or...
Drops of water falling on or sliding over surfaces may leave behind traces of electrical charge, causing the drops to charge themselves. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz have now begun a detailed investigation into this phenomenon that accompanies us in every-day life. They developed a method to quantify the charge generation and additionally created a theoretical model to aid understanding. According to the scientists, the observed effect could be a source of generated power and an important building block for understanding frictional electricity.
Water drops sliding over non-conducting surfaces can be found everywhere in our lives: From the dripping of a coffee machine, to a rinse in the shower, to an...
