There are applications where it would be beneficial to have a self-sustaining, fully embedded monitoring system as part of a structure in order to ensure that structure's integrity. Examples include wind turbines, tidal blades, aeroplane wings, ship propellers and hulls. A project set up under the European Framework 7 has been looking at the possibility of developing such monitoring systems.

Traditionally, transport – and passenger transport in particular – has been provided in a non integrated way. The Transport Systems Catapult has been set up to change this. "We call the market we focus on intelligent mobility," stated Paul Zanelli, chief technical officer, "which is the efficient and cost effective movement of goods and people."

Colonoscopies can be an uncomfortable procedure for patients who may already be worried about what the results may find. The process involves probing the large intestine with a tiny fibre optic camera, known as an endoscope, embedded in a 4ft long, flexible tube.

Since its discovery, graphene – the atom thick carbon material – has been hailed as the heir apparent to silicon. It has much to commend it; an unusual chemical structure means electrons move freely along the plane of the graphene sheet, encountering practically no resistance. But that's also where graphene's problems start. Unlike silicon, it is simply too good a conductor to operate effectively as a switch without some circuit design and materials processing gymnastics.

Once the plain old telephone service, the role of the telephone wire continues to be refashioned. The latest digital subscriber line (DSL) standard being developed – G.fast – uses 106MHz of phone wire spectrum to deliver gigabit broadband, a far cry from its original purpose of carrying a 3kHz voice call. The developments (see fig 1) complement fibre getting ever closer to the home.

No one disputes that carbon nanotubes have the potential to be a wonder technology: their properties include a thermal conductivity higher than diamond, greater mechanical strength than steel – orders of magnitude by weight – and better electrical conductivity than copper.

Mobile device users in the UK are about to be offered mouth watering deals to entice them to shift to faster data rate services as competition finally comes to the 4G market. 02 has just launched its LTE based (Long Term Evolution) services, while Vodafone and 3G UK – the other operators with 4G licences – will follow on shortly as they try to make up ground on Everything Everywhere, which was allowed to use its 1800MHz spectrum last October.

Whatever the problem, or quest for improvement, with image processing, the trend is to try and find solutions in software. The problem is that software complexity turns graphics processors into power hungry beasts.

Dr Sian Fogden was a researcher at Imperial College, studying nanotubes for her PhD, when Linde Electronics became interested in her work. Now Linde Nanomaterials, part of Linde Electronics, is pursuing this line of work in California with Dr Fogden at the helm. The resulting product, a nanotube ink, was launched at NT13 – the international nanotube conference held in Helsinki in the closing days of June 2013.

Gallium nitride (GaN) has been touted as 'the next big thing' in power electronics applications for some time now. In speed, temperature, efficiency and power handling, various implementations of the technology are set to take over as silicon power devices reach their limits, and the hottest topics at recent power exhibitions in the US and Europe have surrounded the introduction of GaN devices.

Since the invention of the battery by Volta in the early days of the 19th Century, users have been looking for more performance. Volta's device was superseded in 1859 by the lead acid battery – a device still in widespread use today. By the end of the 19th Century, the nickel cadmium battery had been developed.

Research has long shown that plants respond better to particular wavelengths of light, specifically in the 400 to 500nm (blue) and 600 to 700nm (red) spectra. Now, the advent of high output, low power, more affordable LED modules configured at specific wavelengths is beginning to revolutionise the horticulture sector.

It has been a continuing trend over the last few decades that electronic devices at the leading edge are designed to be as complex as the manufacturing technology allows. But while the level of device complexity is increasing, so too is the possibility that the parts will not operate entirely as the designer intended.

How easy is it to design a camera that can read or that can decide whether a person's eye is open or shut? This is an important question for design engineers, since computer vision is set to become a required function in many applications which today contain no cameras.

Nothingness might not sound very useful. In fact, the opposite is the case because nothingness – in the form of a vacuum – has played a major role in the history of electronics. Until the invention of the transistor, vacuum tubes were the industry's critical component because they made it possible to amplify, switch and modulate electrical signals.
