In order to store information in the conventional magnetic memories of electronic devices, the materials’ small magnetic domains work by pointing up or down according to the magnetic fields. To generate these fields it is necessary to produce electric currents, but these currents heat up materials and a large amount of energy is spent cooling […]
Cognitive-Related Neural Pattern To Activate Machines
Brain-machine interfaces represent a solution for people with physical difficulties to communicate with their physical and social environment. In this work, researchers have identified a functional brain pattern in the prefrontal cortex, associated with cognitive processes, and have used it to activate a screen on a touch device (an iPad touchscreen). The use of the […]
Distance Wireless Charging Enhanced by Magnetic Metamaterials
Universitat Autònoma de Barcelona researchers have developed a system that efficiently transfers electrical energy between two separate circuits. The system, made with a shell of metamaterials that concentrates the magnetic field, could transmit energy efficiently enough to charge mobile devices without having to place them close to the charging base. The research was published in […]
Most Precise Quantum Thermometer Designed
Researchers from the UAB and the University of Nottingham, in an article published today in Physical Review Letters, have fixed the limits of thermometry, i.e., they have established the smallest possible fluctuation in temperature which can be measured. The researchers have studied the sensitivity of thermometers created with a handful of atoms, small enough to […]
