Prototype Battery Fully Charges in Less Than 30 Seconds

An Israeli start-up is demonstrating a prototype battery able to charge in less than 30 seconds. StoreDot, which showed the battery at this week’s Microsoft Think Next Conference, based it on bio-organic nanocrystals made of peptide molecules. In their demonstration, a Samsung S4 smartphone using the technology went from dead to fully charged in 26 seconds. The item is now roughly the size of a pack of cigarettes. Reducing its size, as well as increasing its energy density, are among the goals of StoreDot, which hopes to commercialize the technology in the next three years, at which time it will likely be twice as expensive as current products. In the past, the researchers have used their peptide-based bio-organic nanocrystals have been used in products such as memory chips and image sensors, and was initially discovered by researchers looking for a cure for Alzheimer’s disease.

Researchers Create Ultrafast Memory Device

Nanyang Technological University and University of California, Berkeley, researchers have constructed a prototype ultrafast, energy-efficient ferroelectric memory device able to use light to read data. Three types of memory chips are commonly available: RAM, ROM, and DRAM, each of which has limitations. Recent research on addressing these limitations has focused on developing an energy-efficient device that is faster and more accurate than RAM. The leading candidate is ferroelectric RAM, which is made with bismuth ferrite and uses magnetic polarization to represent the ones and zeros of binary data. The newly developed FRAM chip uses halogen light to read the polarization.  Shining a light on the material does not disturb its polarization. This would eliminate errors, specifically the erasing of data, that can occur when devices use electricity to read polarization. The researchers claim their device is about 10,000 times faster than DRAM and operates on only 3 volts of electricity, compared to DRAM’s average 15 volts. The next steps toward commercializing the technology include making it smaller. The researchers published their work in the journal Nature Communications. (PhysOrg)(Nature Communications)

Microsoft Whiteboard Automatically Completes Drawings

A prototype interactive whiteboard by Microsoft could complete user diagrams automatically. Users of the device, called SketchInsight, could draw an image on a large touchscreen, and automatically create charts or other diagrams based on preloaded data. The whiteboard creates the chart itself once a user has drawn a symbol on it. A graph, for example, is created by drawing an “l” shape. The user would labels the axes of the chart, which tells the system the datasets needed to populate the chart. SketchInsight is one of many large-screen technologies Microsoft is developing to help users understand big datasets. (BBC)(Wired UK)
