Their ultrathin, conductive, and transparent hybrid NMs can be applied to the fabrication of skin-attachable NM loudspeakers and voice-recognition microphones, which would be unobtrusive in appearance due to their excellent transparency and conformal contact capability. Credit: UNIST
An international team of researchers, affiliated with UNIST has presented an innovative wearable technology that will turn your skin into a loudspeaker. This breakthrough has been led by Professor Hyunhyub Ko in the School of Energy...
Purdue University researchers have created wearable electronic devices that someone can easily attach to their skin. They can be used to monitor physical activity and alert a wearer about possible health risks in real time. Credit: Ramses Martinez/Purdue University
Heart surgery can be traumatic for patients. Having to continuously monitor your status without a doctor when you are back home can be even scarier. Imagine being able to do that with a simple sticker...
The illustration shows the atoms of a gold cone exposed to a strong electric field. We also see the field (around the tip of the cone) that excites the gold atoms. They break almost all their connections to each other and the surface layers begin to melt. Credit: Alexander Ericson
When the tension rises, unexpected things can happen -- not least when it comes to gold atoms. Researchers from, among others, Chalmers University of Technology, Sweden, have now managed, for the first time, to make...
Reducing the impact forces of water entry
When professional divers jump from a springboard, their hands are perpendicular to the water, with wrists pointed upward, as they continue toward their plunge at 30 mph. As they complete what's known as a rip dive,...
Aquatic animals that jump out of water inspire leaping robots
Ever watch aquatic animals jump out of the water and wonder how they manage to do it in such a streamlined and graceful way? A group of researchers who specialize in water entry and exit...
Scientists at the National Synchrotron Light Source II (NSLS-II) -- a U.S. Department of Energy (DOE) Office of Science User Facility at DOE's Brookhaven National Laboratory -- have used ultrabright x-rays to image single bacteria...
The International Prototype of the Kilogram (IPK) is held in an underground vault at the International Bureau of Weights and Measures (BIPM), located in Sèvres, near Paris. Following the decision to redefine the SI kilogram starting 20th May 2019, the definition of the kilogram will no longer be based on the physical artefact called the International Prototype but rather on a constant of physics, as are the other seven base units of the SI. The redefinition of the kilogram marks the end of artefacts used to define our measurement units. Credit: © BIPM
Today, in a landmark decision, representatives from 60 countries voted to redefine the International System of Units (SI), changing the world's definition of the kilogram, the ampere, the kelvin and the mole, forever. The decision, made...
The newly developed face of the Affetto child android robot. Affetto's face was first revealed in 2011. Credit: Osaka University
Japan's affection for robots is no secret. But is the feeling mutual in the country's amazing androids? We may now be a step closer to giving androids greater facial expressions to communicate with. While robots have...
The shape of things to come: Flexible, foldable supercapacitors for energy storage
A team of researchers from the Plasma Physics Research Centre, Science and Research Branch of Islamic Azad University in Tehran, Iran, have discovered a way of making paper supercapacitors for electricity storage, according to a...
Mmore effective hydrogel for healing wounds
Researchers at the University of New Hampshire have created an easy-to-make, low-cost injectable hydrogel that could help wounds heal faster, especially for patients with compromised health issues. Wound healing can be complex and challenging, especially when...
