Desktop 3-D printing in metal or ceramics

These spur gears—seen here with a euro cent coin for scale—have been produced in stainless steel to a space standard of quality using nothing more than an off-the-shelf desktop 3-D printer.

Engineers combine light and sound to see underwater

Stanford University engineers have developed an airborne method for imaging underwater objects by combining light and sound to break through the seemingly impassable barrier at the interface of air and water.

AI-fueled batteries

Machine learning is increasingly being used as a tool that helps researchers discover new materials and compounds for their unique design requirements. This novel approach cuts down the time researchers spend creating and ...

Electronic skin has a strong future stretching ahead

A material that mimics human skin in strength, stretchability and sensitivity could be used to collect biological data in real time. Electronic skin, or e-skin, may play an important role in next-generation prosthetics, personalized ...

Using fabric to 'listen' to space dust

Earlier this month a team of MIT researchers sent samples of various high-tech fabrics, some with embedded sensors or electronics, to the International Space Station. The samples (unpowered for now) will be exposed to the ...

A pocket cooling device based on a cascade mechanism

Recent technological advances have enabled the development of increasingly compact and flexible devices. This includes wearable or portable technology, such as smart watches, earphones or other smart accessories, which can ...

Strengthening homes against earthquakes

Ph.D. candidate Ömer Türkmen, at the TU/e Department of the Built Environment, did extensive testing on a new way of strengthening masonry walls that is cost effective, minimally invasive, easy to install and a great improvement ...
