Walkman series of music phones since 2005 inception, has always been Sony Ericsson's best-selling mobile phone one of the series. Especially within a short period of three years, more than a few 10 million in sales performance, but became a series of Sony Ericsson's development and growth of the camp, the main driving force. Following the series's first five million-pixel mobile phone W902 mobile phone on the network such as four surfaced, the Sony Ericsson official also recently officially confirmed the upcoming release on July 22 the news Walkman series of new aircraft. Accordance with the relevant statement, when the Sony Ericsson Walkman series mobile phones will be the theme of the official release, including W902, W585/595, W302 and W707, including four Walkman phone.

    The upcoming release of four Sony Ericsson Walkman series phones are basically low-end coverage of high school at all levels, and in mobile phone style modeling is also straight, slide and fold three categories ranging. Among them, using candy bar design, and for the low-end market, the overall function of the Sony Ericsson W302 Sony Ericsson S302 specifications and basically not much difference, mainly through the outstanding music features reflect its product positioning. However, the aircraft can be interpreted as though the music version of the S302, but the Sony Ericsson W302 in the overall style but there is a big difference with the former, for example has a slim body and texture-rich metal-style body, in particular, is unique in that key design more with the past, W880 and W890 is almost identical.

    As the low-end positioning's sake, this Sony Ericsson W302 phone's main hardware configurations more general, such as loading the 2.0-inch 176 × 220 pixels, 26 million color TFT screen and built-in 2 million pixel camera. In addition, the aircraft also used the A200 platform, and design highlight the music capabilities, built-in Walkman player is compatible with a variety of music format playback and built-in FM radio function, with stereo Bluetooth output and TrackID track recognition and large-capacity memory card expansion functions.

    As in the past development, code-named "Linda" The Sony Ericsson W595 slider phone was seen as being hot on the market and the successor of the W580 mobile phone upgrade. Although the design of the aircraft in local than in the past there have been some changes, but as a whole or to maintain the original style of the W580 features, such as thin body and a unique design of the navigation keys and so on. However, as an upcoming series of new Walkman phones, Sony Ericsson W595 is still there in some detail many changes, such as the body has 14 mm thickness, and apart from the fuselage, over the last bright colors, the Sony Ericsson W595 is also filled with controversy for the past, mobile phone keypad has been redesigned, but also the layout of the rules in the past, though not dazzling, but they feel superior aspect. In addition, the aircraft also go with the tide for the mobile phone loaded with pairs of speakers, and synchronize the phone's built-in camera Pixels 3.2 million upgrade. However, some unfortunately, still does not provide auto-focus feature is designed somewhat disappointing.
According to the U.S. life sciences news report, August 20, the U.S. Massachusetts Institute of Technology researchers claimed that only half the size of human cells by the virus, micro-batteries ahead of micro-organisms constitute a doctrine.

Massachusetts Institute of Technology engineers has been completed now that the three-part mini-cells in the two-part design, the micro-battery can be implanted medical sensor body or laboratory computer chips to power, and those very small objects. In addition, it can be implanted in other life than imagine the body. It is reported that this micro-battery can be installed in a stamping or printing surface.

    Massachusetts Institute of Technology to teach Paula. Hammond, Angela. Baylor Toru, Chang Ye-ming (phonetic) and the research team together with my colleagues responsible for this study, they noted that, as far as we know, this is for the production and placement of micro-cell electrode first instance of a micro-contact printing, while this is the first time assembly of viruses for micro-battery production, the study published in the "Journal of the National Academy of Natural Sciences," Journal.

    Belcher said, "The current research team has built and tested a micro-batteries, two of which required three parts, the technology itself does not involve any expensive equipment, while the experiment need to be completed at room temperature." Micro-batteries, including two On the contrary electrode - the cathode and anode, their isolation from the electrolyte, in the current state of research, Massachusetts Institute of Technology research team has established a cathode and anode and electrolyte.

    Firstly, the research team at the light, rubber materials, the use of something called "soft lithography" (soft lithography) common techniques to build micro-battery-connector models, these tiny battery connector is only 4-8 microns in diameter. The top of the battery connector, the research team piled up a number of pairs of polymer layer, its role is a solid electrolyte and battery isolation device. Next, the virus self-assembly in the battery connector of the polymer layer at the top, forming the anode. This will form a micro-batteries, then stamped, each battery connector is covered with electrolyte layer and the cobalt oxide anode.

    Hammond explained, and then we manufacture the battery connector stamping, and electrolyte and anode transferred to a platinum structure. Sheet together with the lithium test. At present, the research team focused on the establishment of a full third part of the battery - the cathode, they used viral assembly technique.

    Belcher said, "We are very interested in the use of biological organisms integrate these micro-batteries." It is reported that the study is undertaken by the U.S. Army Research Institute and David. Lucille. Packard Foundation investment completed.
