Without battery-operated wireless transceiver device will come out

United Microelectronics Research Center (IMEC) at the recent International Solid State Circuits Conference reported a power consumption of only 51 micro-watt 2.4GHz (Ji Hezi) / 915 MHz (megahertz) since the alarm receiver. The minutes of low-power developed without Sony VGP-BPS8 Sony VGP-BPS8A battery or can be automatically capture energy opens the door to devices transceiver wireless technology can be widely used in the identification of long range radio frequency (RFID) and logistics, smart buildings and medical services used by the wireless sensor node.

Currently, the battery system of wireless communication in wireless devices do not send or receive data consumes much power, which means that most of the time, the Bluetooth phone or a wireless LAN when you do not work and also the battery access to energy. IMEC developed with ultra-low power consumption and fast response time of the receiver clock can be compared with the equipment transceiver traditional to send or receive data when you need to change.

R & D based on double sampling of new wireless transmitter architecture can overcome the 1 / f noise, 1 / f noise will affect the majority of low-speed (10Kbps to 100kbps) devices transceiver wireless. Therefore, obtaining the same performance as the traditional principle that the device transceiver high data rates of devices has a higher budget power. Double sampling technique, 1 / f noise can be reduced, so that the receiver sensitivity can change with the data rate to increase proportionately. TD347 C1295

Self-clock receiver chip using 90 nanometer digital CMOS technology, the chip area of about 0.36 mm2. Measurements show, 915MHz 100kbps receptors (OOK) modulation of the sensitivity of-75dBm (signal to noise ratio greater than 12dB). When the data rate of 10Kbps and filter by business soundtrack, the sensitivity may increase 5dB. 2.4GHz receiver and 100kbps data rate of 10Kbps cases, the sensitivity of-64dBm, respectively, and-69dBm.

The researchers reported that research in autonomous systems, wireless sensor, the research objective is to develop energy can be made to the environment, instead of using cell systems of wireless sensors. For the digital signal processor, radios transceiver and sensors, power budget of the system of only 100 microwatts. Only 51 micro-watts of ultra-low-transceiver power wireless devices successfully developed towards achieving this goal has taken a major step, which is as long-range RFID, smart lighting, sensor tags and other applications not the battery, opening the door. 371785-001 417066-001

IBM study of conventional materials to product solar cell technology

Documents published in newspaper articles, said it was possible with conventional materials, a relatively efficient manufacturing of solar cells. Such cells may be from 9.6% of solar energy into electrical energy, the photovoltaic conversion efficiency higher than 40% of today’s technologies. ThinkPad R50 battery ThinkPad R51 battery

This conversion efficiency is much higher than silicon cells available on the market, and even comparable to the efficiency of solar cells in thin layers. IBM’s use of traditional materials for the manufacture of solar cells, such as copper, zinc, tin, sulfur or selenium. IBM said that solar energy technologies used in existing equipment often limited its development.

Companies in the solar industry announced they were using cadmium and tellurium thin-film batteries. GE also plans to begin selling next year, batteries cadmium telluride material. Some small companies like Nanosolar, HelioVolt and Miasolé in the production of copper, indium, gallium and selenium solar cells made of alloy material. ThinkPad R52 battery ThinkPad T40 battery

IBM researchers Teodor Todorov, Kathleen Reuter, and David Mitz that the defects mentioned above the battery is to use either the raw materials are scarce, or the impact on the environment. This means that these batteries need to consider the environmental costs. TJWatson Research Laboratory IBM Thomas Theis, director of physical sciences, said: “Of other equally effective battery contained in either very expensive or impact on the environment, or not much room for further improving the efficiency, which makes their commercial scale and large-universal access has become difficult. ” ThinkPad T41 battery ThinkPad T42 battery

Compared to conventional batteries, the benefits of thin-film batteries are to use the equipment is relatively low. IBM solar cells can be used to produce manufacturing techniques at high speed, such as “Rolling Manufacturing Technology” (roll-to-roll manufacturing). U. S. National Laboratory for Sustainable Energy researcher Matthew Beard participated in the research project of IBM, this technology is a breakthrough. ”

Scientists expected that if the technology can achieve a breakthrough, get 12% of the photoelectric conversion efficiency, resulting in economic costs to completely replace the products of existing solar energy. ThinkPad T43 battery ThinkPad T60 battery

The battery or to the end: the quickly charge and discharge plastic come out

For new generations of uninterrupted flow of energy in the G5266 HD438 battery will probably soon be thrown into the dustbin of history. According to the British “Daily Post” recently reported that British scientists have developed a can store and release energy of ultra-thin plastic that, or will completely change the way people use their mobile phones, cars and even clothing approach.

University of London, Imperial College Department of Aviation Half a research team led by Dr. R & D out of the plastic, not real drums, but a super-capacitor circuit similar to the common capacitor.

The researchers first trained two layers of carbon fiber sandwiching a layer of material in the fiber glass, when the sandwich is electricity, electrons with a layer of carbon fiber to another layer of carbon fiber, which produce positive and negative electric charge. When the device is inserted in an electrical device may be the same work as regular batteries. ThinkPad R50 battery ThinkPad R51 battery

The team completed a sample of about 32 square centimeters, and the ultra-thin, with a normal diet for 5 seconds can be filled with electricity and enable LED illumination for 20 minutes. They are currently working with Volvo Car Corporation to launch a period of 3 years, 3 million pounds of investment in the project to prepare such materials for hybrid gasoline-electric, using it to replace the trunk of a Volvo car containing a spare tire hanging metal floor. The researchers said the technology, the future of cars can get energy through the roof and even doors. This also means that cars will be smaller, lighter and more efficient.

The researchers said that the speed of hardware support and discharge the battery faster than normal, and there is no chemical reaction, therefore, have a longer life, will be a very wide range of applications. This means that mobile phones and power for iPod, etc. The duration will be doubled, but also make such electronic gadgets as thin as a credit card. In addition, it can also be used to make flexible computer screen, where people can be folded like paper and a computer to carry, and that the use of computer time will be longer.

In addition, people can also use it to create “wearable electronics“, which in people can be charged when traveling, and heat when the weather cools. hp Pavilion dv2000 battery  hp Pavilion dv6000 battery

The researchers said that so far no one has produced such material, it will be in ten years is expected to replace the battery.

Silicon Valley has developed long-lasting fuel cells, life span up to 10 years

A startup in Silicon Valley companies Bloom Energy has announced the development of breakthrough fuel GK479 FK890 cell for the source server to provide cheap and relatively clean energy. Currently, Google, Bank of America and Wal-Mart and other big companies have tested the device.

Bloom Energy Corporation has received from investors funded 400 million dollars, and spent nearly 10 years to develop a series of fuel cells solid oxide, solid oxide fuel cells are considered the most effective technology, but are the most difficult technology of fuel cells. Bloom, co-founder and CEO K.R.Sridhar said that the new equipment using natural gas to produce one unit of electricity cost of 8-10 cents per share, plus a few prices electricity trade in the city is also cheap.

He said they would provide cheap electricity in industry, rather than an industry fuel cell at low prices. Local Bloom Wednesday in the United States to hold a press conference to announce this new technology, when California Governor Arnold Schwarzenegger and U. S. Former Secretary of State Colin Powell, members of the Board of the Company will present.

However, while that Bloom created fuel cells more efficient, but does not know the scope of enterprise technology, cost and sustainability has been limited to the use of other types of fuel cells would know the potential of the technology company may take many years.

A leading manufacturer of UTC Fuel Cell Power Manager Mike Brown (Mike Brown) said they had spent in the development of solid oxide for 30 years but still at an experimental stage, we can solve the problems of reliability.

Fuel cells are electrochemical reaction through the process, hydrogen, natural gas or other fuels into electricity to provide cheap power to bring hope, while the release of pollutants unless a traditional power plant. However, this battery will need to use expensive titanium and other metals and rare earth materials, making the battery life of their high cost and very short.
