The system use 3D cameras to detect and record gestures

Quality control is a vital part of modern manufacturing. Not only does it decrease the chances of a dissatisfied customer, but it reduces waste and, therefore, cost. However, inspecting products on the assembly line can itself be expensive, time consuming, and not as accurate as it should be. To speed things up a bit, BMW has developed a new system for inspecting bumpers that uses gestures to allow inspectors to literally point out defects.  Read More

The 3D-Lung tumor model helps researchers to test medications (Photo: Fraunhofer IGB)

Researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology in Germany have created a miniature artificial lung that has the potential to significantly improve the process of developing treatments for lung cancer. In addition to the possibility of replacing animal trials currently used to test new medications, the "3D-lung" could be used to expand our understanding of how lung cancer spreads to the rest of the body.  Read More

The cell stacks that are the heart of a home fuel cell system being developed by Fraunhofe...

As the world shifts to alternative forms of energy, ways to make homes less dependent on the grid continue to gather steam. Fuel cells, which are more efficient and have lower emissions than internal combustion engines seem like a logical candidate for taking up the slack, so the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) in Dresden is partnering with the heater manufacturer Vaillant to develop a domestic fuel cell system that uses natural gas to produce both heating and electricity.  Read More

Computer simulation of a wing flex module

We tend to think of aeronautical engineering as having left the birds standing still sometime around the First World War, but since jet fighters can’t perch and quadcopters can’t snag salmon out of a stream, we still have a few things to learn. Taking a couple of pages from the avian playbook, Fraunhofer Institute for Electronic Nano Systems (ENAS) and its partners are developing wing flaps for airplanes that change shape like a bird’s wing for greater efficiency.  Read More

The parallel ordering of liquid crystals make them near-frictionless lubricants (Image: Mi...

The world uses tens of millions of tons of lubricant every year, from the smallest part of a micro-precision instrument to the expansion rollers on the largest bridges. Most are oil based, though others use powders, and even metals, and it’s been that way for decades. That could be changing as the Fraunhofer Institute for Mechanics of Materials, Nematel GmbH, and Dr. Tillwich GmbH have developed a new class of lubricants that are based on liquid crystals instead of oil. According to Fraunhofer, this is the first fundamentally new lubricant developed in twenty years.  Read More

Fraunhofer's thermic-piezoelectric deformable mirror could be applied in high-powered lase...

One cinematic cliché we've all seen is when the hero deflects the villain's dastardly laser beam with a hastily snatched hand mirror, sending it back at his adversary. Physics, ever the wet blanket, says that this is a highly improbable scenario. Focusing high-powered lasers isn't easy. A powerful laser distorts the mirror, throwing the beam off and spreading it out uselessly. To combat this, Fraunhofer is developing a lens that can deform itself to compensate for heating and other distortion factors to keep lasers focused on target.  Read More

How a snake-like robot developed by Fraunhofer winds its way through the narrow openings i...

Although modern jet airliners may be at the cutting edge of technology, assembling them is, in many ways, still as much of a craft as 18th century shipbuilding, requiring loads of skill and manual labor to get the job done. The Fraunhofer Institute for Machine Tools and Forming Technology (IWU) in Chemnitz, Germany wants to bring airplane construction into the 21st century with a snake-like robot that can assemble airplane wings by reaching into narrow, hard to reach cavities.  Read More

The Mobile Authentication via Retina Scanner (MARS) prototype is compact and portable (Pho...

Retinal scans have a lot going for them as a form of identification. You can’t forget your retinas, they're unique, they’re a lot harder to steal than passwords, and Captain Kirk uses them. The problem is, the technology needed to run a reliable retinal scan is often bulky, expensive, and hard to use. Scientists at the Dresden-based Fraunhofer Institute for Photonic Microsystems (IPMS) have shrunk down retinal scanning technology in the hopes of making retinal scans a more widespread identification technology.  Read More

A demonstration of how the phosphorus-laden particles can be removed from water using a ma...

Phosphorus is a mineral that's widely used in fertilizer, which itself has an unfortunate tendency to leach out of farmers' fields and into our waterways. Now, researchers from Germany's Fraunhofer Institute for Silicate Research have devised a method of retrieving some of that phosphorus from the water – thus both reducing pollution, and providing a source of reclaimed phosphorus.  Read More

Gallium nitride transistors enabled the compact design of this 2090 lumen retrofit LED lam...

Although known for long life and low energy consumption, the LED uses a DC power supply, or driver, to overcome its sensitivity to current fluctuations, and it’s the high-frequency, high-speed switching transistors in this driver that’s made the LED so costly for use in large-scale commercial applications dominated by fluorescent and incandescent lighting. But that’s about to change. Fraunhofer researchers are developing a new, more economical means of making the high-performance gallium nitride transistors needed for the LED’s high-efficiency driver.  Read More
