Researchers at the Fraunhofer FEP institute developed a new wearable OLED-based "button" that can be integrated into textiles. The OLEDs can be designed in any shape, be transparent, dimmable and also patterned. There is also a two-color variant.

The Fraunhofer developers say that such elements can be used for fashion trends, branding, safety applications, light therapy and more. The so-called O-Button is based on an OLED deposited on a wafer-thin foil combined with a micro-controller on a conventional circuit board.

The O-Button is not just a research project. The Fraunhofer FEP can supply samples of this to interested companies, can take individualized designs into initial prototypes and can also be contracted for pilot production.
