Eliminating Corrosion Extends Life of Lightweight Batteries

Wearable devices that harvest energy from movement are not a new idea, but a material created at Rice University may make them more practical.

Solar power researchers have traditionally only used the power measurements from single residential solar photovoltaic (PV) systems to estimate the power...

Advancements in zero-emission fuel cells could make the technology cheap enough to replace traditional gasoline engines in vehicles, according to researchers at the...

By adding utility-scale solar farms throughout New York state, summer electricity demand from conventional sources could be reduced by up to 9.6% in some places. But Cornell...

Computers and similar electronic devices have gotten faster and smaller over the decades as computer-chip makers have learned how to shrink individual transistors. Scientists’ pursuit...

With a wide range of healthcare, energy, and military applications, stretchable electronics are valued for their ability to be compressed, twisted and conformed to uneven surfaces without losing...

What if drones and self-driving cars had the tingling “spidey senses” of Spider-Man? They might actually detect and avoid objects better because they would process...

Researchers at University of British Columbia Okanagan’s School of Engineering have developed a low-cost sensor that can be interlaced into textiles and composite materials. While the research...

Rotary Ball Spline

NB Corporation of America (Hanover Park, IL) released a rotary ball spline that can be used for both rotational and linear motion. Applications include SCARA robots, the...

Researchers have developed a new and improved snake-inspired soft robot that is faster and more precise than its predecessor.

In discussing fatigue life, it is important to distinguish between disc springs and conical spring washers, as they differ by design and intended usage. Conical spring washers are...

Employing fluid power to achieve mechanical motion can be implemented via hydraulics using uncompressible liquids or via pneumatics using compressible gasses; typically, air. The latter provides several...

An ultra-low-power hybrid chip inspired by the brain could help give palm-sized robots the ability to collaborate and learn from their experiences. Combined with new generations of...

A new learning system improves a robot’s ability to mold materials into target shapes and make predictions about interacting with solid objects and liquids. The system, known as a...

NASA Goddard Space Flight Center developed gear bearing technology that combines gear and bearing functions into a single unit that significantly improves gear drives for electrical, internal combustion, and turbine motors. The...

EMAG L.L.C. is the U.S. subsidiary of a major German machine tool builder that specializes in machine tools for the production of automotive, off-highway, agricultural, and oil field...

For wheelchair users, the feeling of uneven ground can seem all too familiar. Determined to make ride discomfort a thing of the past, Israel-based SoftWheel has completely reinvented the wheel for a...

An interdisciplinary Northwestern University team has developed a pair of soft, flexible wireless sensors that replace the tangle of wire-based sensors that currently monitor babies in hospitals’...

Early wearable fitness monitoring devices were designed to perform a set of valuable but straightforward activities: tallying the number of steps we take daily, recording the number of hours we sleep,...
