Fuel cell advance a breath of fresh air
A promising alternative to conventional power plants, solid oxide fuel cells use electrochemical methods that can generate power more efficiently than existing combustion-based generators. But fuel cells tend to degrade too quickly, eating up any efficiency gains through increased cost.
Light provides control for 3D printing with multiple materials
3D printing has revolutionized the fields of healthcare, biomedical engineering, manufacturing and art design. Successful applications have come despite the fact that most 3D printing techniques can only produce parts made of one material at a time. More complex applications could be developed if 3D printers could use different materials and create multi-material parts.
Spider silk could be used as robotic muscle
Spider silk, already known as one of the strongest materials for its weight, turns out to have another unusual property that might lead to new kinds of artificial muscles or robotic actuators, researchers have found.
Advancing additive manufacturing by slashing support
3D printing opens up design possibilities that engineers could once only dream of. The technology allows manufacturers to create parts with unique and complex shapes—parts that conventional manufacturing methods such as die casting or injection molding can't produce.
Implantable device aids weight loss
New battery-free, easily implantable weight-loss devices developed by engineers could offer a promising new weapon for battling the bulge.
It's not a shock: Better bandage promotes powerful healing
A new, low-cost wound dressing could dramatically speed up healing in a surprising way. The method leverages energy generated from a patient's own body motions to apply gentle electrical pulses at the site of an injury.
Explaining the plummeting cost of solar power
The dramatic drop in the cost of solar photovoltaic modules, which has fallen by 99 percent over the last four decades, is often touted as a major success story for renewable energy technology. But one question has never been fully addressed: What exactly accounts for that stunning drop?
New material, manufacturing process, uses sun's heat for cheaper power
Researchers have developed a new material and manufacturing process that would make one way to use solar power - as heat energy - more efficient in generating electricity.
New fuel cell concept
In a new approach, inspired by biology a university team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.
Kids connect with robot reading partners
Kids learn better with a friend. They're more enthusiastic and understand more if they dig into a subject with a companion. But what if that companion is artificial?
Wearable device measures tendon tension
For athletes and weekend warriors alike, returning from a tendon injury too soon often ensures a trip right back to physical therapy. However, a new technology developed by engineers could one day help tell whether your tendons are ready for action.
