Robotic insect moves across the water via world-record tech

Water striders are fascinating to watch, as they scoot across the water while supported by surface tension. Scientists have now built a tiny robotic version of the insect, which utilizes a record-breaking actuator to get a move on.Continue ReadingCateg… Continue reading Robotic insect moves across the water via world-record tech

Hyundai unveils car tires with built-in, push-button snow chains

Hyundai has presented a new wheel and tire design that incorporates built-in snow chains that deploy and retract at the push of a button, potentially putting an end to the fiddly, freezing process of wrapping and removing traditional snow chains.Contin… Continue reading Hyundai unveils car tires with built-in, push-button snow chains

NASA-inspired airless bicycle tires are now available for purchase

Two years ago, we heard how the Ohio-based Smart Tire Company was developing shape memory airless bicycle tires. Well, the resulting Metl tires can now be purchased via – you guessed it – a Kickstarter campaign.Continue ReadingCategory: Bicycles, Trans… Continue reading NASA-inspired airless bicycle tires are now available for purchase

KnitDema glove puts the electronic squeeze on swollen fingers

Hand edema, which is a swelling of the fingers due to the accumulation of fluid from injury or disease, is typically treated via a hand massage performed by a therapist. A new finger-massaging glove, however, may offer a less costly and more accessible… Continue reading KnitDema glove puts the electronic squeeze on swollen fingers

Shape-memory implant may keep immobilized muscles from wasting away

When a limb is rendered immobile for long periods of time, its muscles will inevitably begin to atrophy. A new implant could help keep that from happening, however, by mechanically stretching and compressing those muscles.Continue ReadingCategory: Medi… Continue reading Shape-memory implant may keep immobilized muscles from wasting away

Smallest-ever remote-control walking robot uses shape-memory alloy

Researchers at Northwestern University in Illinois have demonstrated the world’s smallest remote-controlled walking robot, at just half a millimeter wide. Such tiny machines can bend, twist, crawl, walk, turn and jump without hydraulics or electricity…. Continue reading Smallest-ever remote-control walking robot uses shape-memory alloy

Active Aero Wheel features brake-heat-activated cooling vents

Although a completely flat-surfaced wheel would be aerodynamic, it would also be hard to keep cool – especially during the braking process. An experimental new wheel rim, however, has cooling vents that open as needed … and they’re activated by heat.Co… Continue reading Active Aero Wheel features brake-heat-activated cooling vents

Shape-memory alloy component could make for quieter aircraft landings

Although an airliner’s engines may be quite loud on takeoff, its wings also create a lot of wind noise when it’s landing. According to a new study, the latter problem could be addressed with the addition of a shape-memory alloy filler within the wing.C… Continue reading Shape-memory alloy component could make for quieter aircraft landings

NASA’s shape memory airless tire tech makes its way onto bicycles

An advanced tire technology developed by NASA for use on planetary rovers could be coming to a bike lane near you, with startup the Smart Tire Company leveraging the technology to introduce an airless alloy tire to the world of cycling. With the elasti… Continue reading NASA’s shape memory airless tire tech makes its way onto bicycles
