Leti and Liten have combined the performance of silicon and the flexibility of printed electronics to functionalize any planar or curved surface, from window glass and smartphone cases to wristbands and robot fingers. The researchers began work on these advances under a Carnot-funded project. Leti made a test vehicle (a silicon chip thinned to 40 microns, encapsulated, and electrically connected to a polymer die in its cleanrooms). The test vehicle was used to validate the concept, which is now protected by three patents.

They are now preparing an operational demonstrator for the end of 2019. It includes a RFID chip and silicon strain sensor integrated into a die, which will be connected to an antenna printed by Liten on a substrate.
