In the search for efficient methodologies focused on up scaling production of low cost functional ceramic oxides, the implementation of Chemical Solution Deposition (CSD) in combination with drop on demand (DoD) inkjet printing technology is a challenge in materials science. When simple additive processing is implemented in continuous reel to reel systems with novel low-cost materials, the potential to further decrease the production costs of the whole manufacturing process is immense.Sets of parallel YBa2Cu3O7−x (YBCO) stripes, 250 nm thick and 150 μm wide, with critical current densities (Jc) of about 1.1 MA/cm2 at 77K and self field are obtained.On the other hand, different designs of magnetoresistive La0.7Sr0.3MnO3 (LSMO) devices with electrical resistances in the range of 10 KΩ including the contact pads, are drawn onto LaAlO3 (LAO) and SrTiO3 (STO) single crystals. We particularly investigate different strategies to increase pattern resolution and accuracy. Preliminary morphological and electrical characterizations of the device on cheaper amorphous, polycrystalline and textured substrates are presented.Therefore, this paper gives a summary of functional ceramic oxides patterning by combining CSD and inkjet printing methodologies onto different single crystal, polycrystalline and textured substrates. The present work demonstrates a powerful method of fabricating multifilamentary YBCO patterned coatings for low losses coated conductors (CC's) and LSMO magnetoresistive analog encoders for position sensing.
