A Swedish SME has developed a new method to manufacture thin, all-organic, lightweight and flexible light emitting patches, which provides a solution for the large unmet need for printable light. The SME has the core competence how to make the individual patch and will, primarily, deliver ink to print the patches, but can also provide equipment components to facilitate production.
The technology behind the patches is light-emitting electrochemical cells (“LEC”), which has been developed by the company founder at the Organic Photonics and Electronics group at Umeå University in Sweden. The LEC can be printed in ambient conditions entirely from solutions.
The market and potential applications are as follows:
Within the medtech/healthcare sector, printable and disposable light can replace clumsy hospital equipment for light treatment of skin conditions, eye disease, baby jaundice, wound healing etc.
The patches can be combined with printed electronics to create applications with indicators, logos and other user interactions for wearables (and other IoT) and for control panels in automotive and white goods.
Packaging for consumer goods, such as fast-moving consumer goods and luxury brand packaging, can be enhanced by lighting features. Security features can also be added for fraud-protection and consumer information. Usage could also spread to functional light, where the patch can be used in combination with different sensors to indicate expired products, or to guide customers to selected products. The new printable light-solution can provide several colours with low driving voltage, 4-9 VDC. A separate power supply is not required if it is integrated with an RFID power harvesting antenna, which is enough to turn on a 10mm x 20mm light patch.
The SME offers manufacturing partners and distributors to incorporate new features in their products based on light, to establish this innovation into the market. Other agreements of interest are within research and technical assistance/cooperation.
