Speedy Laser Mirrors Enable Better Welding

Silicon micromirrors can guide laser beams at extremely high speeds, allowing operators to dose heat input to workpieces with absolute precision. But to date, they have not been robust enough to be used for laser cutting and welding. Researchers have developed fast, durable mirrors that are capable of performing challenging cutting and welding tasks.

3D-Printed Aerogels Improve Energy Storage

A new type of graphene aerogel will make for better energy storage, sensors, nanoelectronics, catalysis, and separations. Lawrence Livermore National Laboratory made graphene aerogel microlattices with an engineered architecture via a 3D printing technique known as direct ink writing. The 3D printed graphene aerogels have high surface area, excellent electrical conductivity, are lightweight, have mechanical stiffness, and exhibit super-compressibility.

Assisting An Aging Population: Designing Medical Devices With Force Sensing Technology

With the geriatric population on the rise, design engineers are challenged with designing responsive, noninvasive, user-friendly medical devices that cater to the needs of an older generation. Patients are looking for cost-effective, easy to use assistive tools that help them regain independence and confidence in their everyday life. Force feedback is a key feature for many of these devices that provide the user and doctor with great insight that ultimately results in better quality of life for the patient. Medical devices with force feedback allow design engineers to create innovative products that differentiate them from the competition.

Micro-Tentacles Help Robots Handle Delicate Objects

Engineers from Iowa State University developed micro-tentacles that enable robots to handle delicate objects. “Most robots use two fingers. To pick things up, they have to squeeze,” said Jaeyoun (Jay) Kim, an Iowa State University associate professor of electrical and computer engineering and an associate of the U.S. Department of Energy’s Ames Laboratory. “But these tentacles wrap around very gently.”

NASA Tests Aircraft Wing Coatings that Slough Bug Guts

Bug guts create drag, and drag increases fuel consumption. But aircraft of the future could be made more fuel-efficient with non-stick coatings NASA recently tested on Boeing’s ecoDemonstrator 757. NASA and Boeing engineers tested non-stick wing coatings designed to shed insect residue and help reduce aircraft fuel consumption. Researchers assessed how well five different coatings worked to prevent insect remains from sticking to the leading edge of the airplane's right wing.

Fuel Cell Carts Deliver Power to Airplane Galleys

Airplane galleys consume a huge amount of power. Additional power units may soon come to the rescue: housed inside trolley carts in the galleys, these units deliver both supplemental power and thus uncouple the power to the cabin and the kitchen from power supplied to the rest of the aircraft. In addition, the cart does not need new approval every time the airplane gets a retrofit or a facelift.
