| Future electronics with super-efficient hard drives: Electricity controls magnetism Posted: 06 Mar 2014 11:27 AM PST Researchers have demonstrated how a magnetic structure can be altered quickly in novel materials. The effect could be used in efficient hard drives of the future. Data on a hard drive is stored by flipping small magnetic domains. Researchers have now changed the magnetic arrangement in a material much faster than is possible with today's hard drives. The researchers used a new technique where an electric field triggers these changes, in contrast to the magnetic fields commonly used in consumer devices. This method uses a new kind of material where the magnetic and electric properties are coupled. Applied in future devices, this kind of strong interaction between magnetic and electric properties can have numerous advantages.  |
| Engineering team increases power efficiency for future computer processors Posted: 06 Mar 2014 06:55 AM PST Scientists have made major improvements in computer processing using an emerging class of magnetic materials called 'multiferroics,' and these advances could make future devices far more energy-efficient than current technologies.  |
| IT security for the daily life: Withdrawing money at cash machines with 'Google Glass' Posted: 06 Mar 2014 06:54 AM PST Mini-computers with head-mounted display like 'Google Glass' don't just alarm privacy activists. Rather, they also enable applications increasing data protection. Computer scientists demonstrate this by combining Google Glass with cryptography methods and novel techniques of image processing to withdraw money at cash machines or to read encrypted documents.  |
| New research could help make 'roll-up' digital screens a reality for all Posted: 06 Mar 2014 06:36 AM PST New technology could make flexible electronics such as roll-up tablet computers, widely available in the near future. So far, this area of electronic design has been hampered by unreliability and complexity of production.  |
