Driven by the development of new functional inks, inkjet‐printed electronics has reached several milestones by moving from the integration of simple electronic elements (e.g., temperature and pressure sensors, RFID antennas, etc.) to high‐tech application fields ( e.g . optoelectronics, energy storage and harvesting, medical diagnosis).

Currently, inkjet printing techniques suffer from spatial resolution higher than several micrometers, a redhibitory threshold for miniaturization and for many applications that require to control organization of constituents at the nanometer scale. In this review, we present the physico‐chemical concepts and the equipment constraints underpinning the resolution limit of inkjet printing method and point out the input of molecular, supramolecular and nanomaterial‐based approaches for their circumvention. Based on these considerations, we propose future trajectories for inkjet‐printing …
