DecoChrom Idea Challenge Winner

We are happy to announce the winners of the DecoChrom Idea Challenge (for more information about the challenge see below). For the selection process, the jury members judged the submissions according to the following criteria:

  • Creativity of the proposed idea
  • How novel is the idea?
  • Is the idea in any way realizable with DecoChrom technology?
  • Does the idea align with the goals of the projects?
  • Will the idea likely make an impact on the respective communities?

The criteria where treated as equally important and not ranked.

We received many submissions with authors having varying backgrounds out of the creative industries ranging from Product Design, Fine Art, Graphic Design and Interaction Design as well as Media Science. After carefully discussing the different submissions the jury selected the two winning submissions:

  • The artist IOxOI – David Jeuniaux with his Pixel/BitArt based idea
  • The project SaveDrop by Herttakaisa Herkkola, Inka Kangasniemi, Maiju Kettunen, Emma Kirjavainen & Aelita Spiridonova


IOxOI (David Jeuniaux)

Op Art/ Pixel Art – print RGB matrix on paper to emulate the color reproduction of a tv screen and combine it with electrochromic display to simulate the other important aspect of tv image, the movement.  RGB line matrix will be fluorescent ink and UV, or electroluminescent light, then the dot matrix will be electrochromic paint.

The reasons for selecting this idea submission as one of the winning elements, were first and foremost the creative element and completely novel aspect that is suggested. The visual element is stunning and adds very well to the capabilities of electrochromic displays.


SaveDrop (Herttakaisa Herkkola, Inka Kangasniemi, Maiju Kettunen, Emma Kirjavainen & Aelita Spiridonova)

SaveDrop is a concept meant to display real-time water consumption while using water. The electrochromic display would demonstrate the amount of water consumed during the day. The system is meant to be easy to install in different locations. Due to its flexibility it will also be suitable for curved surfaces. The display with minimalistic design can be attached to different places in a house making it blend into the background.

The reasons for choosing SaveDrop was beside the powerful idea, the excellent alignment with the projects’ goals. SaveDrop is an excellent example of some of the basic motivations behind the project. The idea demonstrates the decorative aspects while solving a complex problem.


DecoChrom Idea Challenge

The DecoChrom idea challenge is a contest for everybody that has an idea for novel application scenarios for electrochromic displays. Whether it is integrated into an existing product, a complete novel device or simply an electrochromic display in a novel context, we want to see your ideas for the future of electrochromics.

All areas of application and context are welcome, including, but not limited to:

  • Smart Home/Building
  • Smart Furniture
  • Health and Wellbeing

This challenge can help making your ideas a reality.


Please submit a single PDF file that contains a short description of your idea, 2-3 images that visualize your idea and your contact details. If you want to add a short concept video, add a link to a Vimeo or YouTube video.

Your idea must be your own original work. We are not claiming ownership rights to your submission. However, by submitting a submission, you grant us the right to use your submission and its content in connection with this Contest and use your submission on our website and social media channels as well as in Reports for the European commission (you will obviously be credited by name in these cases).

Submit your entry here (submission deadline passed)

Deadline: 20th of January 2020


Our Jury will select two winning entries. The two winners will be notified and receive an Ynvisible Ink-Kit to produce their own electrochromic displays. The winners will be chosen, based on the idea’s novelty and potential impact.



Besides the Ynvisible Ink Kit we are also pleased that our friends from electoninks are supporting the winners with a circuit scribe kit each. This will give the winner the possibility to easily prototype advanced systems combining printed electronics and electrochromic materials!

Furthermore, we will offer the winners as well as other selected contest entries to work together with us to turn their ideas into a working prototype.

The results will be published early February 2020.
