Interactive Label

The demonstrator relies on a circuit mainly consisting of 3 LEDs, 3 organic thin-film transistors, and a printed pressure sensor on plastic. Depending on the pressure (weak or strong) you apply on a designated field, the 3 LEDs light up gradually driven by 3 transistors.

It depicts the unique features accessible by printed electronics - thin, lightweight, conformable/flexible on plastic substrate. This system can be applied to any package to add additional features for the OEM as well as for the consumer – in our case a viral marketing via social media. You push as hard as necessary to let the LEDs light up at the flavor you prefer. Take a picture and post it via Instagram to influence the next flavor to come.

Core of the demonstrator is an interactive label enabled by the integration of organic thin-film transistors and piezoresistive sensors on foil. The transistors implemented in top-gate architecture feature a BASF p-type semiconductor with excellent ambient stability. The response characteristics of the printed pressure sensor can be easily tuned to suit a variety of applications.

These pressure sensors can be integrated into various future-oriented applications. For any querries you may have, please contact us. We look forward to hearing from you!
