An electrically-activated adhesive tape incorporating metal strips has been developed for ...

Prefabricated houses are made up of separate pre-assembled modules that are joined to one another on-site – those modules, in turn, are made up of various wooden components that are typically nailed (or sometimes stapled) together in a factory. The wood used in the frames of the modules must be reasonably thick, in order not to split when the nails are driven in. This places some limitations on design possibilities. Now, however, German scientists have developed an alternative to those nails: electrically-activated adhesive tape.  Read More

The “intelligent door seal system” automatically lets fresh air into a crowded room when c...

If you’re in a confidential meeting with the boardroom door closed, the air can get stale pretty fast. Should it be too cold outside to crack any windows, or if the room simply has no windows, then opening those isn’t a choice. That’s why Germany’s Fraunhofer Institute for Microelectronic Circuits and Systems has teamed up with the Athmer Company to create an “intelligent door seal system.”  Read More

A sheet made up of the polymer opals

Some of the most vividly colored materials in nature, including things like butterfly wings, don’t obtain their color from pigment. Instead, their internal structure reflects light at a given wavelength, producing a specific color. Opals are another example of something that utilizes this effect. In collaboration with Germany’s Fraunhofer Institute for Structural Durability and System Reliability, scientists from the University of Cambridge have now copied the colorful nanostructure of the opal. The result is a flexible, colorful material that won’t fade over time, that changes color when stretched, and that could have many applications.  Read More

If you thought 5G wireless was fast at one Gbit/s, how does 40 Gbit/s sound? That's the new wireless data transmission record set by a team of engineers in Germany using integrated solid state mm-wave transceivers. This data transmission rate was demonstrated over a distance of 1 km (0.6 miles) and it is hoped that such links could be used to close gaps between optical networks in rural areas at a fraction of the cost of installing optical fiber.  Read More

Scientists in Germany have developed a protective glove that warns lab workers of toxic su...

Laboratories that deal with dangerous chemicals devote a lot of time and money to ensuring the work environment is safe. Since many toxic substances lack a noticeable smell or color, the trick is finding a detection method that alerts employees to their presence as quickly and clearly as possible. Scientists at the the Fraunhofer Research Institution for Modular Solid State Technologies may have found a simple answer to that problem in the form of a protective glove that immediately changes color when it comes into contact with hazardous materials.  Read More

Cars and lasers, together again (Photo: pop culture geek)

Researchers at the Fraunhofer Institute for Physical Measurement Techniques have come up with a car-mounted laser scanner the size of a shoe box, that can survey the contours of road surfaces at speeds of up to 100 km/h (62 mph). The system detects potholes and other road damage in need of repair. According to the Institute, the Pavement Profile Scanner (or PPS) has surveyed 15,000 km of road since mid-2012, in which time it has proven cheaper, faster and more accurate than existing systems which require hefty attachments to the carrier vehicle.  Read More

The new batteries were developed at the Fraunhofer Institute for Material and Beam Technol...

Technology has advanced markedly since the dawn of the silicon age, but our portable gadgets and gizmos are still largely held back by the limitations of their power source. Scientists at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden report progress in this regard, with the development of a new longer-lasting lithium-sulfur battery that has the potential to outperform lithium-ion batteries, at a lower cost.  Read More

Some of Fraunhofer's printed thermoelectric generators, wrapped around a sample component

Thermoelectric materials, putting it simply, are able to generate electricity via differences in temperature. If thermoelectric felt were used to make a jacket, for instance, it could generate a current using the temperature gradient between the warm interior and cold exterior of the garment. Like many such promising technologies, however, the cost of thermoelectrics is something of an issue ... although thanks to a new process developed at Germany’s Fraunhofer Institute for Material and Beam Technology, that might not be the case for much longer.  Read More

Fraunhofer's W-band radar is equipped with a three-channel antenna with dielectric lenses ...

Researchers at the Fraunhofer Institute for Applied Solid State Physics (IAF) have developed a lightweight, compact radar that can “see” through non-transparent materials and whiteout snow conditions. The compact radar operates at frequencies of 75 to 110 GHz in the millimeter range W-band of the radio spectrum. Radars at this frequency can not only identify small objects up to three kilometers (1.8 miles) away, but they can also penetrate all manner of non-transparent, dielectric, and non-metallic materials, such as clothing, plastic surfaces, paper, wood, snow and fog.  Read More

AiQ's BioMan fabric monitors vital signs such as heart rate, respiration and skin temperat...

Wearable electronics like headphones and watches have long been a common inclusion in many an active person's tech cache. Such devices roll the function of electronics into a comfortable, ergonomic package that can travel far distances at fast speeds. The next generation of wearable electronics will become even more wearable and functional, shedding some of the bulky casing and integrating directly into clothing. From smart socks to hot jackets, the future of technology is molding itself around your body.  Read More
