05:20 pm Development of the electronic Christmas Card
Mr Laszlo Racz,
Allami Nyomda Plc., business development advisor, Hungary
Presenters: Laszlo Racz (Allami Nyomda), Chris Giacoponello (Ntera) and Risto Huvila (Enfucell)
Proposed lenght of presentation: 30 minutes (10 minutes for each gentleman)
Abstract:
Allami Nyomda decided to develop an electronic Christmas Card product that was distributed during the holiday season in 2010. With a press of a button, the
electrochromic display delivered our Seasons Greetings to our clients. All electrical components in the Card was manufactured using printed electronics technologies
(battery, display, circuit and push buttons), the presentation will go over the design, the manufacturing and integration stages of the development. Chris and Risto will go
over shortly the display and battery technologies as well that were used in the Card.
05:40 pm MetaPaper ? Cellulose sheets to filter electromagnetic waves
Dr Guy Eymin Petot Tourtollet,
Centre Technique du Papier, Director, France
The paper and board industry is undergoing changes with the increase of the production capacities in Asia or in Eastern Europe. As a result, this imposes to a specific
sector of the industry to turn to higher added value products. Among them, we have proposed to work on a key-concept to perform selective anti-Wifi or anti-GSM papers.
As a mater of fact, the wireless communication technologies are in full expansion and this changes our environment which is surrounded by a multitude of electromagnetic
waves (mobile phones, Wifi, WiMax, Bluetooth, RFID?). There is a need to filter some of the latter for individual and material protection but also for data security. For
example, theatres, hospitals must remain « quietness » electromagnetic areas; some electronic systems requires protection against degradation or malfunctioning. Data
security is also an important application, particularly for companies which use Wifi networks. A physical protection is the best protection against hacker.
An efficient protection solution is the Faraday room but it is highly expensive, not easy to implement and it blocks all radiations. Cell-phone jammers exist but they do not go
in the electromagnetic « quietness » direction.
We propose a paper material functionalised to ensure selective frequency filtering. Electromagnetic waves are either disperse or reflected by it. It has the well known
qualities of paper, such as low cost, renewability and it is a recyclable resource. This technology has been implemented thanks to printed electronic techniques. It can filter
both Wifi and GSM frequencies at the same time, or only one frequency. Attenuation up to 30dB has been experimentally reached. This application is generating numerous
high-added value products.
