PolyIC, BASF, Evonik Industries, Elantas Beck and Siemens have announced the launch of a new German Federal Ministry of Education and Research (BMBF)-sponsored alliance project called MaDriX to advance the development of high-performance printable Radio Frequency Identification (RFID) tags. […]
PolyIC leads the consortium engaged in the three-year joint project. The total investment sum amounts to some €15 million, with the BMBF contributing approximately €8 million. The project is funded as part of the BMBF’s 5th Framework Program “Key Technologies – Research for Innovations, Communications Technology Sector.” The German Aerospace Center, DLR, is acting as project sponsor. With MaDriX, the companies involved in the alliance and the federal ministry will secure Germany’s current leadership as a research base in the printable electronics sector. […]
The close cooperation between the companies involved is a key to the success of the MaDriX project. PolyIC engages with the issues of component characterization, process development and setting up demonstrators. BASF, Evonik Industries and Elantas Beck will supply new materials to produce semiconductors and insulators for use in electronic circuits. Siemens is developing new real-time visual print inspection processes for quality control in the printing process. A number of universities and research institutes are also involved in the MaDriX project.
New Scientist is reporting on printable batteries with carbon nanotube (CNT) electrodes.
The batteries were created by George Gruner and colleagues at the University of California in Los Angeles, US, and use the same zinc-carbon chemistry as ordinary non-rechargeable batteries.
To make the battery, a layer of nanotubes is first deposited in the form of “nanotube ink” onto a surface. This layer acts as the charge collector, which removes current from the battery.
Next, a layer of nanotube ink mixed with manganese oxide powder and electrolytes, which carries charge within the cell, is applied on top. This layer acts as the cathode. Finally, a piece of zinc foil – the anode – is applied.
“The batteries are similar to conventional batteries,” says Gruner, “with the electrically conducting nanoscale networks replacing conventional metals and electrodes.”
The researchers also made supercapacitors using the inking technique and plan to combine these with batteries for applications requiring more power.
Furthermore, since both printed batteries and supercapacitors can be made entirely at room temperature, it should be possible to mass-produce them using established printing methods, Gruner says.
Professor Gruner is also Chief Technical Officer of Unidym Inc a company he funded in 2005 which focuses on nano-structured materials applications for flexible/transparent electronics.
This subsidiary of Arrowhead Research is developing printed carbon nanotube (CNT) technology for applications such as transparent electrodes, thin film transistors, and fuel cells.
The work has been published in Applied Physics Letters.

Lead investors from prior rounds also participated, including Draper Fisher Jurvetson (DFJ), Asenqua Ventures, New Enterprise Associates (NEA) and 3i. Other participating current investors include Vanguard Ventures, Chevron Ventures, Massachusetts Green Energy Fund, NGEN Partners and Angeleno Group. The financing was agented by Lehman Brothers.
PolyIC, “The chip printers”, are announcing two product lines: PolyID® (RFID) and PolyLogo® (with additional display function).
Applications of products from the PolyID® and PolyLogo® lines will be presented at OEC [Organic Electronics Conference] 2007. PolyIC presents applications in the fields of brand protection, voucher systems, marketing, and logistics.
Within the PRISMA (Printed Smart Labels) project, which is funded by the German Federal Ministry of Education and Research and has PolyIC as its consortium manager, all tickets to the Organic Electronics Conference will have a PolyID® tag attached to them. The tickets will be evaluated with a radio frequency reader at 13.56 MHz. This ticketing field test is being coordinated by Bartsch GmbH.
The steady progress en route to products at PolyIC can also be seen with the results in the laboratory. Thus, 32- and 64-bit RFID chips have been produced in the clean room. This success shows that the production of RFID chips with more memory capacity on the basis of the polymer semiconductor polythiophene is possible.
Konarka (organic photovoltaics) and Toppan Forms (Data Print Services and information management services)
have signed a joint agreement to accelerate the development, manufacturing and commercialization of polymer-based organic photovoltaic (OPV) technologies for consumer and electronic applications. Under the agreement, the mutual goal is to bring Konarka’a organic photovoltaic material, Power Plastic®, to market.
“Konarka’s Power Plastic is flexible, thin, printable and low in cost, providing our organization with promising new business opportunities as we strive to become an integrated information management service company,” commented Masanori Akiyama, president and CEO of Toppan Forms. “With the full-fledged advent of the ubiquitous society under way, we need an ever-present power technology that can be integrated with pervasive networked devices for information collection and distribution. We are delighted to collaborate with Konarka, the world leader in OPV technologies, to accelerate the commercialization of this transformational power technology to the market place.” […]
“The partnership with Toppan Forms represents a key milestone for the commercialization of Power Plastic,” commented Rick Hess, president and CEO of Konarka. “This relationship enables each company to focus its expertise and resources on key product development processes, continuing our go-to-market strategy of partnering with leading global companies for a variety of applications.”
According to the NewScientist, full-colour photonic crystal displays could be on the market within two years. A team of Canadian researchers have developed a reflective display based on silica microspheres which can produce the whole visible spectrum without the need for colour filters.
The researchers stretch the crystals by bonding them to an electroactive polymer that expands when a voltage is applied to it, causing a change in the crystal structure. “By gradually increasing the voltage, we can span the whole visible spectrum, and even the UV and IR ranges. Such full-colour tuning is unprecedented,” says Arsenault, who has co-founded a start-up company called Opalux to commercialise the technology.
The crystals could be used to make full-colour flexible electronic paper, small displays, and large roadside billboards, say the researchers. But this will involve scaling up the process, a task that has proven challenging for other display technologies.
[Update:]
The Opalux web page has a few more details on the P-Ink (photonic ink) display technology:
The materials are based on highly reflective synthetic opal. Colors produced are brilliant and pure. Other features:
1. Full color display from single material for low materials and production cost.
2. Meet signage needs in size from shelf edge to highway billboards.
3. High brightness, peak reflectivity up to 95%.
4. Low power consumption.
Low voltage and current during switching.
Minimal power consumption when image is static.
5. Sub-second switching speed.
6. Heat management through controllable IR reflectivity.
7. Applicable on rigid or flexible substrates.
8. Lightweight, rugged, durable, and damage tolerant.
9. Costs scales only linearly with size.
Researchers at Rensselaer Polytechnic Institute have developed thin, flexible energy storage devices consisting of more than 90 percent cellulose. The paper is infused with aligned carbon nanotubes (electrodes), and an electrolyte (e.g. an ionic liquid). The technology allows to fabricate batteries, supercapacitors, or devices which combine both functions.
According to the press release, the devices can be biocompatible
and these new hybrid battery/supercapcitors have potential as power supplies for devices implanted in the body. The team printed paper batteries without adding any electrolytes, and demonstrated that naturally occurring electrolytes in human sweat, blood, and urine can be used to activate the battery device.
“It’s a way to power a small device such as a pacemaker without introducing any harsh chemicals – such as the kind that are typically found in batteries — into the body,” Pushparaj said.
Regarding manufacturing:
The materials required to create the paper batteries are inexpensive, Murugesan said, but the team has not yet developed a way to inexpensively mass produce the devices. The end goal is to print the paper using a roll-to-roll system similar to how newspapers are printed.
The NewScientist is reporting on colloidal photonic crystals consisting of dispersions of magnetic iron oxide particles with a charged surface coating, developed by Yadong Yin and colleagues at the Department of Chemistry at University of California, Riverside.
The charged particles repel each other but their packing can be influenced by applying a magnetic field. Tuning the spacing of the particles in the colloidal crystal, by varying the magnetic field strength, changes the wavelength of the reflected light.
The crystal reflects brilliant colours from red to violet as the magnetic field strength increases (see image, right). But, when the field is switched off, the crystal reverts back to its original brownish colour.
“This is the first report of a photonic crystal that is fully tuneable in the visible range of the electromagnetic spectrum,” says Yin.
“We see applications in various areas, including sensors, optical switches and flexible colour displays,” he told New Scientist. “For example, the system can be used to make extra-large displays or posters to replace expensive LCD monitors. And, because the colour is based on reflection, it is better for outdoor applications than current LCD displays that perform poorly in direct sunlight.”
Cartamundi, Europe’s largest manufacturer of playing cards and card games, and Thin Film Electronics, developers of printed organic memory devices,
have entered into a commercial License Agreement and a joint R&D Program.
Cartamundi will use Thinfilm’s patented technology and will now enter into a joint R&D project with the objective to include memory capabilities for the development, manufacturing and sales of products in the markets of trading and collectable cards, retail and private label cards, casino cards, promotional cards and cards for games.[…]
Johan Carlsson, CEO of Thin Film Electronics stated that “[…] Cartamundi is the undisputed leader in the market of cards and games, producing over 10 billions of cards annually, making them the ideal partner specialised in high volume production of cards.[…]”
“[…] Thinfilm’s printable re-writable memory technology will enable us to add value by including a functionality that has been asked for by our customers. […] Our goal is to be in production, and to supply our customers with this new feature, already next year.” commented Chris Van Doorslaer, CEO of the Cartamundi Group.
The joint development agreement will build on Thinfilm’s intellectual property for soluble memory materials, as well as extend Solvay’s intellectual property for functional polymer materials. Under the agreement, Solvay Solexis could acquire certain production and commercialization rights to Thinfilm’s memory technology.
The 2.5-inch prototype display supports 16.8 million colors at a 120 x 160 pixel resolution (80 ppi, .318-mm pixel pitch), is 0.3 mm thick and weighs 1.5 grams without the driver.
The prototype, as well as technical details were presented at the SID conferernce. Apparently the display is driven by pentacene TFTs with a mobility of 0.1 cm2/Vs.
Each subpixel (red, green or blue)is driven by a two-transistor, one-capacitor PMOS voltage programming circuit. The display operates at a frame rate of 60 Hz with a signal voltage of 12 V.
Sony uses a top-emission structure for its OLED displays, meaning they have driving transistors on the bottom and emit light from a top OLED layer. […] The structure reportedly allowed the engineers to fabricate the electrodes before fabricating the organic TFT layer, without damaging the semiconductor layer.
The latter is achieved by depositing the pentacene on a patterned, negatively-sloped layer acting as a “built-in shadow mask”.
the market for OLEDs used in displays and lighting applications is expected to reach $10.9 billion ($US) by 2012 and grow to $15.5 billion by the year 2014.
The report discusses the use of OLEDs for mobile devices, flexible/rollable displays, and lighting applications.
