Highly conductive organic metal looks promising for disposable electronic devices

Highly conductive organic metal looks promising for disposable electronic devices | Sciences & Technology | Scoop.it

"(Phys.org) —Although organic materials are often used as semiconductors, such as in organic LEDs and organic transistors, organic materials that have an electrical conductivity as high as that of metals are still very scarce. One problem with developing organic metals is that there is a tradeoff in terms of their crystalline structure: a high crystallinity is required for high conductivity, but is detrimental to the materials' processability. (...)"

Electrostatics do the trick: Simple model describes what happens between organic semiconductors and metals

Electrostatics do the trick: Simple model describes what happens between organic semiconductors and metals | Sciences & Technology | Scoop.it
Organic semiconductors allow for flexible displays, solar cells, and other applications. One common problem in these devices, however, is the interface between the metallic contacts and the organic semiconductor material, where undesirable losses occur. Now researchers have shown what these losses depend upon.

10 Arduino Projects That Simplify Electronics Hacking

10 Arduino Projects That Simplify Electronics Hacking | Sciences & Technology | Scoop.it
The best way to celebrate Arduino is to learn about its best projects and applications.

 

"Saturday marks World Arduino Day, an eponymous celebration of the first decade of the open-source single-board microcontroller designed for do-it-yourself electronics projects.

Developed in 2004 for Italian design students, Arduino quickly became a favorite for builders and makers all over the world. With a built-in set of inputs and outputs that can be directly connected to sensors, Arduino allows for projects that interact with the environment outside the tiny microcontroller.

For this reason, many compare Arduino to Raspberry Pi, but Arduino is not a self-sufficient computer like the Pi. What Arduino can do is make electrical engineering ridiculously easy..."

Healable Supramolecular Polymers as Organic Metals - Journal of the American Chemical Society (ACS Publications)

Healable Supramolecular Polymers as Organic Metals - Journal of the American Chemical Society (ACS Publications) | Sciences & Technology | Scoop.it

"Organic materials exhibiting metallic behavior are promising for numerous applications ranging from printed nanocircuits to large area electronics. However, the optimization of electronic conduction in organic metals such as charge-transfer salts or doped conjugated polymers requires high crystallinity, which is detrimental to their processability. To overcome this problem, the combination of the electronic properties of metal-like materials with the mechanical properties of soft self-assembled systems is attractive but necessitates the absence of structural defects in a regular lattice (...)"

Origami unfolds a new world of shape-shifting electronics

Origami unfolds a new world of shape-shifting electronics | Sciences & Technology | Scoop.it
Researchers are using the geometry of paper folding to come up with futuristic antennas that can retract and compress.

 

When talking about the intersection of art and science, Stavros Georgakopoulos likes to quote Albert Einstein, who once said, "I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge."...
