Any individual who takes advantage of a smartphone will probable be acquainted with NFC technological innovation, which is applied for these kinds of matters as contactless payments, data sharing amongst gadgets and secure logins. To show the versatility of the technological innovation when combined with printed circuitry, Prelonic has produced the Paper Piano.
Austrian tech company Prelonic was started in 2007 to build and manufacture flexible printed electronic modules, such as displays, batteries and sensors. The firm’s very first product is known as PIP, or Prelonic Interactive Paper, which brings together printed circuitry and NFC to give customers a new way to interact with cell products.
The Paper Piano is a demonstration of that technological know-how, and reminds us of Catarina Mota’s Piano Box hack from 2012, but in its place of applying copper tape, LEDs and an Arduino Mega to operate the exhibit, the Prelonic idea takes advantage of PIP and a smartphone.
The corporation commenced by printing a very simple keyboard template on a sheet of paper utilizing a typical laser printer. Conductive carbon was then printed on the back again of the sheet, and a very simple circuit structure printed on a independent sheet. A tiny NFC chip was connected to the underside of the keyboard template, and this sheet placed on top of the circuit layer to kind the interface.
To make music, a smartphone working a companion app is positioned to the left of the printed keyboard so it can be resting on the NFC chip – a individual electricity resource is not desired for the Paper Piano, as ability is shipped to the circuit through the phone’s antenna.
When a user touches any of the 8 white keys printed on the sheet with fingertips (the black keys do not look to bring about independent notes for the functions of this demonstration), corresponding keys on the smartphone exhibit are highlighted and notes sounded by way of the handset’s speakers.
The Paper Piano serves as a basic case in point of doable apps in marketing, schooling and gaming only, and is not available for sale. A paper-slender QWERTY keyboard could be a practical implementation maybe, liberating up cherished smartphone display area and making for a extra snug typing experience. Or possibly a greetings card where printed graphics could be applied to navigate an online photo album exhibited on a phone’s display, or management a streamed playlist.
“It is a generally printed hybrid machine, which allows you to play on an 8-critical piano tunes by way of your cellular phone,” explained firm CEO, Friedrich Eibensteiner. “It is definitely only an example what’s feasible in this know-how environment.” A movie of the Paper Piano venture can be viewed by means of the source link beneath.
