X-ray vision: New augmented reality system shows doctors what’s under your skin without a scalpel

A new technology, called ProjectDR, allows clinicians to observe patients’ internal anatomy without the need for them to go under the knife. It allows medical imaging such as computed tomography (CT) scans and magnetic resonance imaging (MRI) information to be shown directly on a patient’s body in a way that moves as the patient does. […]

Researchers develop flexible carbon nanotubes that be worn on your finger

In an article in NanoWerks, Japanese researchers successfully tuned carbon nanotubes in order to create terahertz detectors that can flex and wrap around body parts. Their results could lead to the eventual use of terahertz electronics in wrap-around devices, wearable technologies, and photonic devices that cover large areas. Carbon nanotubes are a type of carbon […]

Researchers develop high-speed electronics using graphene

Is there anything graphene cannot improve? Swedish researchers recently used the wonder material to enable electronics that work at terahertz speeds. In an article in Chalmers Microtechnology and Nanoscience Department News, they combined graphene transistors and plastic substrates to create a malleable electronic detector that detects terahertz radiation. The graphene-based detector is the first of […]

Scientists develop an extremely small and sensitive chip that can detect you by your smell

Following a disaster such as an earthquake, search-and-rescue (SAR) dogs are often brought in to locate people trapped beneath the rubble. Their life-saving efforts may soon be supported by a new detection device that can sniff out the scent of humans just as keenly as dogs can, an article in Science Daily states. Developed by […]

Scientists create an electronic nose that can smell potential hazards such as spoiled food

Your smartphone may soon be able to catch a whiff of anything nasty in the air. German researchers have created a computer chip-sized electronic nose that can learn from the scents it encounters, an article in Alpha Galileo reported. The olfactory sensor is part of the Karlsruhe Institute of Technology (KIT)’s “smelldect” project. It can […]

Small, flexible sensor being developed to detect specific chemicals or viruses

Health professionals will one day be able to hunt down the tiniest of chemicals and pathogens, thanks to a new sensor developed by Chinese researchers. According to an article on ScienceDaily, the sensor is small and flexible enough to fit inside small spaces, such as blood vessels. Furthermore, its sensitivity allows it to perform numerous […]

New graphene gas sensor inspired by dog noses

Man’s best friend enjoys one of the best noses on the planet. That’s why a Chinese-led study based its newly-developed electronic nose on a dog’s nose by using biomimetic graphene materials, reported a Nanowerk article. A dog’s excellent sense of smell comes from the hundreds of millions of capillaries that line the inside of its nose. The large […]
