Pian’OPV, the piano that can detect light variations

23/04/2019 ASCA® Sensor

One of the particular features of the ASCA® organic photovoltaic film, in addition to its ability to produce electricity, is its capacity to detect light variations, and therefore to act as a sensor. To illustrate this function, the ASCA® Solutions Lab, our design and engineering department dedicated to helping you successfully carry out your projects, has designed this 8-key piano: the Pian’OPV.

A very different piano from the “classic” piano.

Based on a wooden structure and designed by a cabinet maker from La Haye Fouassiere, near Nantes, this piano follows the style of a traditional grand piano. But it works in a completely different way.

Unlike a synthesiser, for example, which emits sound whenever a key is pressed, the Pian’OPV incorporates ASCA® organic photovoltaic modules in each key.

Passing your hand over one of the keys will cause a voltage drop in the OPV module. An electrical signal is then relayed to the membrane of a buzzer to generate a sound at a predefined frequency.

This prototype includes 8 notes to provide the whole C scale.

A photovoltaic piano equally at home indoors and outdoors

Thanks to the ability of the ASCA® organic photovoltaic film to function in low light intensity, this piano is able to function just as well both indoors and outdoors, to the delight of pianists and music lovers!

This concept has been developed by the ASCA® Solutions Lab in order to demonstrate a concrete application of the ASCA® organic photovoltaic film.

Choosing to use ASCA® also gives you the choice from a range of services, from the simple provision of ASCA® film to the complete management of its integration into your application or product, from the design phase to the manufacturing process.
