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

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
Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
