电子墨水:“纸”上弹琴不再是梦想

【电子墨水:“纸”上弹琴不再是梦想】通过将电子墨水打印在塑料胶片上,剑桥石墨烯中心的科学家研制出一种透明钢琴键盘,可以用来演奏音乐。这种胶片上有用石墨烯为原料的电子墨水。他们认为石墨烯可以用来打印其他电子设备,如心脏监护器和其他小巧的感应器。与其他传导性的墨水相比,这种新型材料价格低廉,环保,打印之后不需要额外处理。

 

The paper-thin printout piano that can play music thanks to ELECTRONIC INK

  • Scientists from the University of Cambridge's Graphene Centre created the keyboard from graphene-based electronic ink printed on a plastic film
  • They think graphene could be used in printed electronic devices such as heart monitors and other thin sensors
  • The new material is cheap, environmentally stable and does not require much processing after printing in comparison to other conductive inks

Electronic ink printed on a plastic film has been used to make a transparent keyboard that can play music.

Scientists have demonstrated a new method of printing graphene-based ink on the flexible instrument, which they say could be used to make inexpensive printed electronics.

They believe graphene could be used in printed electronic devices such as heart monitors and other thin sensors.

Dr Tawfique Hasan, Dr Felice Torrisi and Professor Andrea Ferrari at the University of Cambridge's Graphene Centre, invented the graphene-based ink and said just like graphene, the material has a number of interesting properties, including flexibility, optical transparency, and electrical conductivity.

The scientists designed their piano in collaboration with Novalia Limited and its keys are made from graphene-based inks, which have been printed onto a plastic film.

These keys, working as electrodes, are connected to a simple electronic circuit-board, a battery and speaker.

When a person touches a graphene electrode, the amount of electrical charge held in the key changes.

This is then detected and redirected by online canadian pharmacy the circuit to the speaker, creating the musical note.

Other conductive inks are made from precious metals such as silver, which makes them very expensive to produce and process, whereas graphene is both cheap, environmentally stable and does not require much processing after printing.

 

The scientists said graphene ink is superior to conductive polymers in terms of cost, stability and performance.

The research team have also developed a flexible prototype digital display, which uses conventional printable materials, but with a transparent, electrically conductive graphene layer on top.

The graphene layer is not only flexible but also more conductive and transparent than the conventional polymer it replaces.

They believe the simple displays can be used in a wide range of smart packaging applications such as toys, labelling and board games.

'Both of these devices show how graphene could be printed on to a whole range of surfaces, which makes it ideal for printed electronics,' Dr Hasan, the lead researcher behind the prototypes, said.

'For example, it might eventually be possible to print electronics on to clothing and to make wearable patches to monitor people with health conditions, such as a heart problem,' he added.

Another potential application of the technology could be cheap, printable sensors, which could be used to track luggage around an airport to ensure it is loaded on to the correct plane, or to follow products across a production and supply chain, the team said.

 

The result is that each printed laser can be designed to give out its own, unique optical signature.

Because lasers can be printed on to all sorts of surfaces, including plastic, paper, metal and glass, the technique could be used to authenticate a wide range of products.

Dr Gardiner said:'Every year, hundreds of thousands of people are sold fake pharmaceuticals under the mistaken belief that they will help them, while counterfeit products cost companies hundreds of billions of pounds.'

'We think that our printed lasers could be used to protect both products and people.'

The prototypes were developed within the University’s Electrical Engineering Division and the teams are now working with partners in industry with a view to bringing them into commercial use.
