Li-Fi

An alternative to wifi, faster, doesn’t congest the existing network and no issues related to health security. These are the promises of Li-Fi or communication in visible light. this technology are developping by several start-up around the world and begins to be adopted by industrial. Li-Fi for light fidelity aims to make the light communicating. The first adavantage is the debit 10 time faster than wifi. Li-Fi uses visible wavelength, the range of visible wavelength are wider than radio which allows not to buy user licence for bandwidth. safety is enhanced because light visible light can’t throuth walls or humans tissus.

For future use Li-Fi will be coupled with wifi, wifi stays essential for outdoor application and long distance communication.

blocks high – tech

Toys with high technology are not those that we believe. Instantly we think to game console but perhaps not as Lego. Some model are really complex and big and users don’t find specific pieces in catalog so passionated can create them own Lego by using CAO and 3D printers.

Since 1947 Ole Kirk Christiansen revolutionizing the Lego (“leg godt” = “play well” in Danish). Today Lego offers 53 shades of colors. Lego are using a panoply of electronic and pneumatic system to be able of create realistic model.  400 billion of blocks of Lego had been created that 62 by people all around the world.

 

China industrialized graphene

Graphene is a substance made of pure carbon, with atoms arranged in a regular hexagonal pattern similar to graphite.

Graphene should be become the new silicon for electronic application.

China builds a factory of graphene in Cixi. Industrial Ningbo Moxi thinks to be able to produce 300 tons per year. In 2011 a first project demonstrated a production of 30 tons. Graphene is really expensive today 1 kilogram is 800 000 dollars. With this new factory Ningbo Moxi provides to decrease production cost to 500 dollars per kilogram…

A pathway to overcome the silicon

Today power electronic components are made in silicon. Silicon is a cheap product and easy to use but he has significant thermal stresses.

CEA LETI works to overcome the silicon by using nitride of gallium (GaN). GaN can work at higher temperature that silicon so we reduce the need for cooling. CEA LETI produce and test wafer of 200mm since July 2012 by using silicon deposition machine converted.

Three industrials partners are interesting by this technology: Renault for automobile, Schneider Electric and Safran for aeronautic. The project will end horizon 2017.

Breakers for electrical grid

It’s a major innovation for safety of electrical grid.

Breakers working on continue current (DC) and very high voltage has been developed by ABB. According to a Suisse’s specialist this new technology is able to cut the current generate by a nuclear in 5 milliseconds.

The time for a bee to flapping this wing!

To perform these specifications technique and electronic power devices are the state of art. Technology is promising in context of the evolution of high DC for electrical networks.

Storage: Optical discs to high capacity

 

Folio Photonics is a spin ‘off of Case Western Reserve University of Cleveland. Today they develop a new generation of optical discs able to storage one to two To. They use yarrow of storage layers using polymer of polyethylene glycol doped with fluorescent subtract. Each data storage layer is isolated with a film of 3.1µm of polymer.

Folio Photonics insist about the simplicity of this technology. Layer deposition is made like DVD or Blu Ray and we can read this optical disc with a laser already use in public. In a future of 3 years it should be possible to market this technology.

 

Nanoimprint Technology

This video describes how work and what applications are target by this technology.

An industrial process to imprint nanostructures has been developing in 2012 by Imre (Institute of Materials Research and Engineering. Base in Singapore Imre is one of the most active institutes of the area. Earliest this year, they created a consortium with worldwide industrials (Japan, South Korean German, USA). Instead of writing or deposit by inkjet, this approach imprints a Nano metric pattern in a resin. A roll-to-roll process is used for pressing pattern. There are many applications for this technology like unreflective films for screen or solar panels. This technology can be used to create specific coating avoiding bacterial infection. A plastic unreflective with only 0.09% of reflecting has been created today.

 

Betavoltaic Battery

City Labs’s company obtains an authorization to commercialize a new kind of battery. These generators use radioactive source for created an electrical current. Tritium isotope employed for manufacture battery is slightly radioactive when he shifts to helium 3.

Betavoltaic power sources have a lot of advantages: first of all lifetime is 20 year and the nuclear reaction doesn’t emit heat or radiation. Batteries can be recycled.  Technically speaking we can use this battery on large range of temperature pressure and shook; they can deliver 0.8 to 2.4 Volts and 50 to 350 Nano amperes.

The energy quantity limited promises these batteries for specifics applications like temperature and pressure sensors or medical and clock alimentation.

Introduction

Hello,

During my training courses, I assume to present to you some technological stuff in research and developpement. Weekly I will showing to you new technology around optical, electronical and green energy. I think to have an interest to new technology is essential for all engineer whatever your speciality. It is the purpose of this blog, showing you my research on the technology of tomorrow.

I hope you should find an interest to discover goals and performances of this futur product.
