“For the first time, researchers have fabricated sensing elements known as fiber Bragg gratings inside optical fibers designed to dissolve completely inside the body. The bioresorbable fiber Bragg gratings could be used for in-body monitoring of bone fracture healing and …
“Perovskite solar cells are an alternative to conventional silicon solar cells, poised to enter the market with their high power-conversion efficiencies (above 22% now) and lower capital expenditure and manufacturing costs. One of the main methods for depositing perovskite films …
“Rutgers engineers have invented a “4D printing” method for a smart gel that could lead to the development of “living” structures in human organs and tissues, soft robots and targeted drug delivery. The 4D printing approach here involves printing a …
“In a world in which we use devices that we do not necessarily trust, can there be any privacy? Yes, and that’s precisely what device-independent quantum cryptography achieves. New work now shows how this ‘ultimate’ level of communication security …
“Using a new technique they call ‘in-air microfluidics’, University of Twente scientists succeed in printing 3D structures with living cells. This special technique enable the fast and ‘on-the-fly’ production of micro building blocks that are viable and can be used …
“Chinese researchers use a powerful new technique to describe mathematical features of a network. Over the past few decades, topology—a branch of mathematics dealing with shapes that can be turned into other shapes by processes like bending and stretching …
“For decades, materials scientists have taken inspiration from the natural world. They’ll identify a biological material that has some desirable trait — such as the toughness of bones or conch shells — and reverse-engineer it. Then, once they’ve determined the …
“Automation-intensive sectors such as the automotive industry are not the only ones to rely on robots. In more and more agricultural settings, automation systems are superseding strenuous manual labor. As part of the EU’s CATCH project, the Fraunhofer Institute …
“Because of their high precision and speed, Delta robots are deployed in many industrial processes, including pick-and-place assemblies, machining, welding, and food packaging. Starting with the first version Reymond Clavel developed for a chocolate factory to quickly place chocolate pralines …
“Current computer systems represent bits of information — the 1’s and 0’s of binary code — with electricity. Circuit elements, such as transistors, operate on these electric signals, producing outputs that are dependent on their inputs. As fast and powerful …
