What is it with traffic lights? They often make me see red and seem to be stuck on that colour. They just don’t seem to have kept up with today’s traffic flow and demands on road space. [ + ]

With the combination of flexibility, relatively simple fabrication processes and low power requirements, CdSe nanocrystal circuits could pave the way for new kinds of devices and pervasive sensors. [ + ]

By fabricating graphene structures atop nanometre-scale ‘steps’ etched into silicon carbide, researchers have for the first time created a substantial electronic bandgap in the material suitable for room-temperature electronics. Use of nanoscale topography to control the properties of graphene could facilitate fabrication of transistors and other devices, potentially opening the door for developing all-carbon integrated circuits.

The award-winning Tesla Model S car is built by a company whose aim is to accelerate the world’s transition to affordable electric mobility. However, the man behind the company name was basically a mad scientist. Interesting, prolific, but pretty nuts. [ + ]

Rather than just being something that can infect you, your dog or your computer and make you all sick, a new breed of viruses is able to generate harnessable electricity. [ + ]

Ten thousand working transistors placed on a single chip using standard semiconductor processes. [ + ]

For the first time, researchers have powered an implantable electronic device using an electrical potential - a natural battery - deep in the inner ear. [ + ]

Researchers have developed a solar cell made entirely of carbon, an inexpensive substitute for the pricey materials used in conventional solar panels. [ + ]

Researchers at Rice University in the US have developed a lithium-ion battery that can be spray painted onto virtually any surface. [ + ]

Sensors and other electronics are usually made of rigid and stiff material such as metals and plastics - they cannot be stretched, twisted or thrown and should be handled with care. But that is about to change with the advent of stretchable electronics. [ + ]

Sechan Electronics is a contract manufacturing services company committed to developing, testing and manufacturing military electronics systems and subsystems for the US Department of Defense and Prime Contractors. When Sechan need a replacement for its paper-based defect mapping process, it chose Aegis’s Quality System - a decision that has paid off handsomely for the company. [ + ]

Using a new method for precisely controlling the deposition of carbon, researchers have demonstrated a technique for connecting multiwalled carbon nanotubes to the metallic pads of integrated circuits without the high interface resistance produced by traditional fabrication techniques. [ + ]

Using an outdated mobile phone and a simple sensor to measure respiration rates, an Australian student is showing how electronic engineers can contribute to society. [ + ]

The dilute magnetic semiconductor gallium manganese arsenide could open up an entirely new class of faster, smaller devices based on ‘spintronics’. Materials of this type might be used to read and write digital information, not by using the electron’s charge, as is the case with today’s electronic devices, but by using its ‘spin’. [ + ]

The adoption of the ISO standard initially gave rise to major concerns about an increase in development costs and device die sizes within the semiconductor industry. [ + ]
