Electronic ink printed on a plastic pcb board film has been used to make a transparent keyboard that can play music.
Scientists have demonstrated a pcb board 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 circuit board devices such as heart monitors and other thin sensors pcb board. 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 circuit board. The scientists designed their piano in collaboration pcb board 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 pcb board 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 the circuit board to the speaker, creating the musical note pcb board. 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 pcb board. This flexible piano This flexible piano is made from graphene-based inks, which have been printed onto a plastic film. The keys work as electrodes and are connected to pcb board a circuit board, battery and speaker. When a person touches a graphene electrode, the amount of electrical charge held in the key changes and when it is detected it its redirected to the speaker to play a note.
Graphene flexible screen The scientists believe graphene could be pcb board used in printed electronic devices such as heart monitors and other thin displays. The flexible material is similar to circuit board graphene and has a number of interesting properties, including flexibility, optical transparency, and electrical conductivity pcb board 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 circuit board 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 pcb board 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 pcb board airport to ensure it is loaded on circuit board to the correct plane, or to follow products across a production and supply chain, the team said. printed laser Each printed laser can be designed to give out its own, unique optical signature, which its team of creators hope will prevent the sale of counterfeit goods.
A separate team of researchers at the University pcb board has created a detection device that uses printed lasers to identify counterfeit goods, which could help make products ranging from banknotes to designer handbags more resistant to fraud circuit board. Dr Damian Gardiner, who led the project, said the anti-fraud detector demonstrates an approach that could be employed to identify fake pharmaceuticals and currency, as well as high-value goods. It works by exploiting an existing method for printing liquid crystal lasers with inkjet printers, which gives the user pcb board a very precise level of control over the lasers pattern and colour combination. The detector takes advantage of this by shining a second, laser pulse onto the printed one. It then reads the wavelength of the light emission from the printed laser through a piece of dedicated circuit board software and reproduces that reading as a pattern on a spectrograph. fraud laser Lasers can be printed on to all sorts of surfaces, including plastic,pcb board paper, metal and glass, the technique could be used to authenticate a wide range of products. Here a scientist demonstrates how the technology could be used to detect fake banknotes circuit board.
The result is that each printed laser can be designed to give out its own, unique optical signature pcb board.
