Wireless Sensor Networks (WSN) could involve billions of sensors which are needed on utility assets, buildings, pollution monitors, traffic control systems, in agriculture and much more, but adoption has been hindered by conventional primary batteries, which will eventually need replacing and therefore cannot be fitted and forgotten for a long period.

The brain of any electronic device is the circuitry that operated the machine. Without the circuitry, the device is not even worth the cost of the plastic that it is made of. Any electronics device requires some kind of battery or it is nothing more than a paperweight. Recently, some new technology was created by scientists from the University of Pennsylvania that will no longer require a device to use a battery as the power can come from light-powered circuitry.

Leoni, the leading provider of cables and cable systems to the automotive sector and other industries, now offers a solid aluminium conductor for the motor vehicle industry to wire the battery as an alternative to the common copper cable. It can be shaped in three dimensions and weighs only about half as much as the conventional component. Leoni will present this product for the first time at the IAA International Motor Show in Frankfurt, together with other lightweight construction solutions.

Like some tantalizing cursed treasure, boron nitride nanotubes have been tempting researchers with their promise of high heat tolerance, which makes them excellent candidates for components in the next generation of microscopic-scale high efficiency electronics.  But for years the tiny nanofibers, which are similar to carbon nanotubes, have lead researchers down one blind alley after another. tweetmeme_url="http://cleantechnica.com/2010/01/28/carpet-of-boron-nanotubes-could-lead-to-new-generation-of-nano-scale-electronics/"; The fact is that boron nanotubes are much harder to produce than carbon nanotubes.   They won’t catch on until that obstacle is overcome - and it seems that a team of researchers at Michigan Technological University has done just that.  Working with the same instrumentation used for carbon nanotubes, the team has developed a way to grow virtual “Persian carpets” of boron nitride nanotubes in the lab, paving the way for their commercial use.

With copper costs continuing to rise, Delphi Automotive is introducing an Aluminum Cable that performs comparably to traditional copper core cable without the added cost. The technology, which is also lighter than copper cable, is now in production and will be introduced on 2012 model year vehicles.
