The smallest Christmas card in the world

Scottish scientists claim to have produced the world's smallest Christmas card, which is only twice as large as human hair.

BBC reported that the type of Christmas card is super tiny innovative products of nanotechnology engineer from the University of Glasgow, Scotland. It is actually a tiny piece of glass with a Christmas tree.

" A Christmas card of this kind is 200 micrometres wide and 290 micrometres in length ," said David Cumming, a member of the research team . The width of a human hair is about 100 micro-meters . "

Due to its small size, it is necessary for the 8,276 tiny cards to fill the surface of a normal postage stamp. " You can even fold more than half a million cards on a standard A5 Christmas card, but signing that is a real challenge ," Cumming added.

The colors of the card are made by a process called " proton gene resonance " in a sample aluminum film made by the James Watt Nanomaterial Center.

Speaking to the press, representatives of the invention team at the University of Glasgow revealed, the super-tiny card was born to prove the nanotechnology " world 's leading". " Our nanotechnology is one of the best in the world, but sometimes it's kind of tricky for the public to understand the capabilities of this technology, " said Cumming .

We decided to produce this Christmas card as a simple way to express exactly how our technology is. The process of creating greeting cards takes only 30 minutes ... The design of the card is more time consuming than the production . "

According to scientists, the ultra-small Christmas card is just a simple demonstration and nanotechnology has many important applications in reality. The electronics industry is benefiting from micro and nano-fabrication technologies by using it in biotech sensors, optical filters and lighting control.

Applications of nanotechnology are important in the future development of the digital economy and can eventually be incorporated into cameras, TVs and computers to reduce production costs.
