Coral tentacles inspire bio-sock shown to treat Deep Vein Thrombosis

By - February 10, 2015 2 Pictures
The onset of Deep Vein Thrombosis (DVT), whereby a clot forms in the veins and obstructs blood flow, is a legitimate concern for people unable to move their legs. The condition can become truly life-threatening if the clot finds its way into the pulmonary artery, which carries deoxygenated blood to the lungs. Looking to mitigate the dangers of this condition, researchers have developed a specialty sock inspired by the tentacle movements of coral that is designed to stimulate blood circulation through the body.

Sea turtle robot charges its own batteries

By - December 30, 2014 2 Pictures
They may be slow on land, but when they're in the water, sea turtles are fast and maneuverable – qualities that are also desirable in underwater robots. Additionally, the robotic equivalent of a turtle's streamlined shell could be stuffed full of electronic components and batteries. It shouldn't come as a surprise, therefore, that both ETH Zurich and the ARROWS project have recently created their own turtle-bots. Now, the National University of Singapore has announced its own entry in the field, that can self-charge its batteries while at sea. Read More

New robotic walker helps patients walk with a natural gait

By - November 26, 2014
It can be a laborious business, teaching people such as victims of strokes or brain injuries to walk again. Often, multiple physiotherapists are required to hold patients up while they walk on a treadmill, while also manually moving their legs to achieve the proper gait. Soon, however, a robotic walker developed at the National University of Singapore could make the process considerably easier. Read More

Nanoelectronic circuits reach speeds of 245 THz

By - April 21, 2014
Researchers at the National University of Singapore (NUS) have designed and manufactured circuits that can reach speeds of up to 245 THz, tens of thousands of times faster than contemporary microprocessors. The results open up possible new design routes for plasmonic-electronics, that combine nano-electronics with the fast operating speed of optics. Read More

Fluorescent sensor indicates presence of date-rape drug within 30 seconds

By - March 27, 2014
Central to the dangers of so-called "date-rape" drugs is the fact that they are difficult to detect. Indeed, GHB, one of the most commonly-used of such drugs, is both colorless and odorless. A team of researchers from the National University of Singapore (NUS) has developed a fluorescent sensor which, when mixed with a drink containing GHB, changes color within 30 seconds, potentially alerting people soon after their drink has been tampered with.

New MRAM technology promises memorable consumer electronics experience

By - December 30, 2013
Back in 2005, Professor of Physics Johan Åkerman touted magnetoresistive random access memory (MRAM) as a promising candidate for a "universal memory" that could replace the various types of memory commonly found alongside each other in modern electronic devices. A team of researchers from the National University of Singapore (NUS) and Saudi Arabia's King Abdullah University of Science and Technology (KAUST) has now developed a new type of MRAM that could see Åkerman's vision become a reality.

Computer rendering of taste is on the tip of the tongue

By - November 28, 2013 8 Pictures
Today is Thanksgiving Day in the United States, a holiday in which we celebrate the blessings granted by Life, the Universe, and Everything. A central part of Thanksgiving traditions involves a massive feast, often featuring turkey or ham, and a selection of delicious side dishes. It may soon be possible to virtually experience such a repast as enjoyed by a character in a movie or a video game, aided by a new method for digitally actuating the sense of taste through electrical and thermal stimulation of the tongue.

SESTO gives hospital beds a power boost

Being both long and heavy, wheeled hospital beds aren't known for being easy to move around. It typically takes at least two people to push and guide one down the corridors, and two people aren't always available in a busy hospital. Using the new SESTO system, however, one person should be able to wrangle a bed without difficulty. Read More

Artificial muscles could allow robots to lift 80 times their own weight

By - September 10, 2013
It's a classic science fiction scene: an android is injured and its human-like exterior is laid bare to reveal the metallic gears and cables of its true mechanical nature. The future is, unsurprisingly, not likely to match this scenario as our ability to mimic biology with innovations like artificial muscles improves. The latest breakthrough in this field comes from the National University of Singapore’s Faculty of Engineering where researchers have developed a “robotic” muscle that extends like real muscle tissue to five times its original length, has the potential to lift 80 times its own weight and holds out the promise of smaller, stronger robots capable of more refined movements.
