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.

IDTechEx Printed Electronics USA 2013 award winners

Each year the Printed Electronics industry recognizes and awards outstanding achievement to those involved in the rapidly growing printed electronics business. The annual awards were announced at the tenth annual IDTechEx Printed Electronics event this week in Santa Clara, California - the world's largest event on the topic.

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.
