Flower power: Transparent rose-petal skin enhances solar cells

We humans tend to pat ourselves on the back when we make strides in converting the sun's light into energy through solar technology, but plants have been doing much the same thing on Earth for thousands of years. Realizing this, a team of scientists lifted an imprint off rose petals and created a film that significantly boosted the efficiency of solar cells.Read More

Nanoscale lattice is world's smallest

Scientists from Karlsruhe Institute of Technology have created a tiny lattice they claim is the world's smallest. Formed with struts and braces measuring less than 10 micrometers in length and less than 200 nanometers in diameter, the 3D lattice has a total size of less than 10 micrometers, but boasts a higher specific strength than most solids.Read More

Proximity Hat presses users' heads to guide them

We've already seen a number of systems designed to alert blind users to objects in their path, and most of those systems use cues such as audio tones or vibrations. A scientist at Germany's Karlsruhe Institute of Technology, however, has taken another approach. Florian Braun's "Proximity Hat" applies pressure to the wearer's head, in the direction of the obstacle.Read More

Sensors to detect smouldering cables before they catch alight

They say that where there's smoke there's fire, but when it comes to electrical systems, by the time the smoke is detected, it's often too late. To raise the alarm early, a team of researchers from the Karlsruhe Institute of Technology and Karlsruhe University of Applied Sciences have developed hybrid sensors that detect gases given off by overheated plastic cables before too much damage can occur.Read More

All-optical permanent on-chip memory paves the way for faster, more efficient computers

A new non-volatile optical memory has been created by researchers working at the Karlsruhe Institute of Technology (KIT) and the universities of M√ľnster, Oxford, and Exeter. Utilizing innovative phase-change materials to store information, the new device promises to significantly improve processing speeds by effectively eliminating the existing bottleneck of having to convert optical signals into electrical signals for storage and then back again for transmission.Read More

Snake skin-inspired steel could lead to better hard drives

When it comes to human phobias, snakes are frequently found toward the top of the list. But despite the negative reputation, these reptiles make up an important part of our ecosystem while exhibiting some very unique biological aspects. The way snakes move across surfaces is pretty incredible, and researchers at the Karlsruhe Institute of Technology (KIT) have figured out how to potentially use that feature to enhance everything from hip prostheses to computer hard disks.Read More

New process prints electroluminescent layers directly onto three-dimensional objects

Electroluminescent (EL) panels are found in many electronics applications, particularly as backlighting for LCD displays, keypads, watches, and other areas requiring uniform, low-power illumination. While relatively flexible, when EL panels made from plastic are bent too sharply, fractures and a severely diminished output usually result. As a result, EL panels have generally been restricted to flat or slightly curved surfaces. However, researchers from Karlsruhe Institute of Technology (KIT) and Franz Binder GmbH & Co have now developed a new manufacturing process to print EL panels directly onto the surface of almost any convex and concave shape. Even, apparently, onto spheres.Read More
