New graphene transistor created with record high-switching performance
Graphene has already brought us the world’s smallest transistor, a triple-mode, single transistor amplifier and a supercapacitor that can store as much energy as a battery while recharging in seconds. And these are sure to just be the tip of the iceberg. The latest breakthrough from the wonderful world of graphene is a new graphene field effect transistor (GFET) that boasts a record high-switching performance. The device promises improved performance for future electronic devices and means graphene could potentially replace silicon, or at least be used side by side with silicon, in electronic devices.

By measuring the differences between emitted sound pulses and their echoes sonar is able to detect and identify targets such as reefs, wrecks, submarines and fish shoals. However, standard sonar has limitations in shallow water because bubble clouds, which result from breaking waves or other causes, can scatter sound and clutter the sonar image. Inspired by the exceptional sonar capabilities of dolphins, scientists have now developed a new underwater device that can outperform standard sonar and detect objects through bubble clouds.

If you’ve watched any spy movies, then you’ll know that biometric security systems can recognize individuals based on physiological traits such as their fingerprints, handprints, faces and irises. Well, you may soon be able to add “ears” to that that list. Scientists from the University of Southampton’s School of Electronics and Computer Science have used a program called image ray transform to achieve a 99.6 percent success rate in automatically locating and isolating ears in 252 photos of peoples’ heads.

Brain-Computer Interfacing (BCI) is a hot area of research. In the past year alone we’ve looked at a system to allow people to control a robotic arm and another that enables users to control an ASIMO robot with nothing but the power of thought. Such systems rely on the use of an electroencephalograph (EEG) to capture brain waves and translate them into commands to control a machine. Now researchers at the University of Southampton have used a similar technique to show it is possible to transmit thoughts from one person to another. Read More
As the incidence of drugs escalates in 21st century living, their detection and analysis have become increasingly important. Sport, the workplace, crime investigation, homeland security, the pharmaceutical industry and the environment are just some of the high profile arenas in which analytical testing has provided an important investigative tool for uncovering the presence of extraneous substances. Now there's a new scientific magazine entitled Drug Testing and Analysis which will explore the analytical techniques used to determine controlled and potentially controversial compounds. As a promotion for the first issue, publishers Wiley-Blackwell have made public a podcast of an interview with Professor Richard Holt of the University of Southampton on the current state of human Growth Hormone use, abuse and detection in sports.

A giant rubber tube known as the “Anaconda” may present an viable solution to the challenge of generating electricity from the power of ocean waves. Under development in the UK, the simple design means it would be cheap to manufacture and maintain, resulting in clean electricity at a lower cost than other types of wave based energy production.

A researcher at the University of Southampton in the UK has developed a new self-powered sensor that would allow surgeons to monitor progress during knee operations. The Serial In-vivo Transducer (SIT) uses thick film technology and could measure tendon force during Anterior Cruciate Ligament reconstruction; a common procedure among athletes. Read More
July 6, 2007 Researchers at the University of Southampton have developed a kinetic energy generator which derives electrical energy from the vibrations and movements that occur within its environment. Developed by Dr Steve Beeby and his team at the University's School of Electronics & Computer Science (ECS), the tiny generator (less than 1 cubic cm in size) is 10 times more powerful than anything yet developed in the field and could form the basis of technology for self-powered pace makers and other embedded applications that require periodic replacement of batteries.
