Engineers show how to optimize carbon nanotube arrays for hot spots

Experimental evidence and computer simulations suggest how to grow structures with the best trade offs between three desired characteristics: strength, flexibility and the ability to dissipate heat.

Natural deep-sea batteries

Exploring the deep oceans presents huge technical challenges, many of which could be overcome if there were some cheap and efficient way to deliver power to machines while at depth.

Droplet simulation technology for printed electronics

The developed program allows numerical simulation, with the use of a commercial personal computer, of the shapes of ink droplet placed on a flat substrate surface that includes discontinuous boundaries between hydrophilic and hydrophobic areas, whereas such a simulation has been difficult so far.

Crystal film growth: nanosheets extend epitaxial growth applications

Molecularly thin two-dimensional crystals can alleviate the lattice matching restrictions of epitaxial crystalline thin film growth, as reported by researchers in Japan.

Inkjet-based circuits at fraction of time and cost

Researchers from Georgia Tech, the University of Tokyo and Microsoft Research have developed a novel method to rapidly and cheaply make electrical circuits by printing them with commodity inkjet printers and off-the-shelf materials.

First polymer LED that stays lit up when stretched and scrunched

Researchers say that they have produced the first polymer organic light-emitting diodes (PLEDs) that can be stretched while lit.

Imperceptible electronics that are lighter than a feather

Researchers have succeeded in developing the world's lightest and, simultaneously, the world's thinnest mechanically flexible touch sensor system.

Exotic alloys for potential energy applications

The search for thermoelectrics, exotic materials that convert heat directly into electricity, has received a boost from researchers at the California Institute of Technology and the University of Tokyo, who have found the best way to identify them.

Printed electronics in East Asia: change of direction

Variously called Printed, Flexible or Organic Electronics, it is one of the fastest growing technologies in the world. It is of vital interest to industries as diverse as consumer goods, healthcare, mobility, electronics, media and architecture.

First impressions from Printed Electronics USA 2012 California

Printed electronics has reached its tipping point as evidenced by the world's largest event on the topic, Printed Electronics USA, now taking place in Santa Clara California, staged by the leading analysts on the subject, IDTechEx.

Highlights from Printed Electronics Asia 2012

IDTechEx held Printed Electronics Asia 2012 in Tokyo, Japan last week. This is part of the World's global event series on the topic with other events in USA (Dec 5-6) and Europe (April 17-18). Senior-level attendees from some of the biggest chemical, equipment and electronics companies were present from 23 countries, with 50% of attendees from Japan, and 66% of attendees from East Asia.

Tohoku University and imec partner on research and collaboration

Tohoku University and imec have signed a collaboration agreement in the presence of his Royal Highness Prince Philip of Belgium during the Belgian economic mission to Japan.

Real Time Locating and Wireless Sensor Networks - Rapid Advances

In the past, too much use of RFID has involved sensing items and conveyances only when they pass very near to the occasional interrogator. Heroic assumptions are then made about what happened in between. Was it destroyed, perhaps by overheating? Is it still there? Is it intact?

New topics covered at Printed Electronics Asia

While some involved in OLEDs and OTFTs are moving out of the business of printed and potentially printed electronics, work on inorganic materials and compounds is increasing. The IDTechEx Printed Electronics Asia event in Tokyo will give a balanced view with many presentations being World firsts.

Printed Electronics uses more inorganics and composites

Printed electronics is using more inorganics and composites in the quest for higher performance, lower costs, finer feature size, stretchability and creation of radically new components such as memristors, supercabatteries and metamaterials.

Cheap stretchable displays possible with elastic CNT-based conductor

Using the same rubbery CNT-based conductor they developed a few months ago, researchers at the University of Tokyo made a stretchable display.

Highlights from IDTechEx on Printed Electronics Asia 2008, Tokyo

Companies such as Toppan Forms, Panasonic, Dai Nippon Printing, Sony, Samsung, Toyota, Mitsubishi Plastics, Brother Industries, Teijin, Konica Minolta, Mitsui, Toshiba and Honda attended Printed Electronics Asia 2008
