Paper-thin piano demonstrates the ability of printed electronics and NFC


Anybody who makes use of a smartphone will possible be accustomed to NFC expertise, which is used for things like contactless funds, knowledge sharing between units and safe logins. To show the flexibility of the expertise when mixed with printed circuitry, Prelonic has created the Paper Piano.

Austrian tech firm Prelonic was based in 2007 to develop and manufacture versatile printed digital modules, together with shows, batteries and sensors. The agency’s first product known as PIP, or Prelonic Interactive Paper, which mixes printed circuitry and NFC to provide customers a brand new option to work together with cell units.

The Paper Piano is an indication of that expertise, and reminds us of Catarina Mota’s Piano Field hack from 2012, however as an alternative of utilizing copper tape, LEDs and an Arduino Mega to run the present, the Prelonic idea makes use of PIP and a smartphone.

The corporate started by printing a easy keyboard template on a sheet of paper utilizing a typical laser printer. Conductive carbon was then printed on the again of the sheet, and a easy circuit structure printed on a separate sheet. A tiny NFC chip was hooked up to the underside of the keyboard template, and this sheet positioned on prime of the circuit layer to type the interface.

To make music, a smartphone working a companion app is positioned to the left of the printed keyboard so it is resting on the NFC chip – a separate energy supply shouldn’t be wanted for the Paper Piano, as energy is delivered to the circuit through the cellphone’s antenna.

When a consumer touches any of the eight white keys printed on the sheet with fingertips (the black keys do not seem to set off separate notes for the needs of this demonstration), corresponding keys on the smartphone show are highlighted and notes sounded through the handset’s audio system.

The Paper Piano serves as a easy instance of potential functions in promoting, schooling and gaming solely, and isn’t accessible on the market. A paper-thin QWERTY keyboard may very well be a helpful implementation maybe, liberating up treasured smartphone display house and making for a extra snug typing expertise. Or possibly a greetings card the place printed graphics may very well be used to navigate a web based photograph album displayed on a cellphone’s display, or management a streamed playlist.

“It’s a primarily printed hybrid gadget, which lets you play on an 8-key piano music through your cell phone,” stated firm CEO, Friedrich Eibensteiner. “It’s actually solely an instance what’s potential on this expertise world.” A video of the Paper Piano undertaking might be seen through the supply hyperlink beneath.
