“…The Nanojet process decreased the generation of ewidths down to 20 µm. [26] In this work, the aerosol-based deposition system Nanojet by IDS [25] was employed to print the sensor structure. This process was based on creating a constant aerosol stream from a liquid ink containing functional particles in the nanometer range.…”

The knowledge of the operating conditions in rolling bearings in technical applications offers many advantages, for example, to ensure a safe operation and to save resources and costs with the help of condition monitoring and predictive maintenance procedures. In many cases, it is difficult to implement sensors to measure the operating conditions of the rolling bearing, for reasons such as inaccessibility of the mounting position or non-compliance with installation space neutrality, which influences the sensor on the measuring point. Printed sensors using a digital deposition process, which can be used in very narrow design spaces, offer advantages in this respect. So far, these sensors have not been established in rolling bearings, so there is potential for technical application. This paper discusses the fundamental advantages and disadvantages as well as the challenges of the application, and it demonstrates the feasibility under isolated boundary conditions by applying a printed strain gauge sensor to the outer ring of a cylindrical roller bearing NU210 in an experimental setup to measure the strain under load. In this setup, the outer ring is deformed by 2 mm under an increasing radial load using a hydraulic press, and the strain is measured. Both a commercial reference sensor and a FE-simulation are used to validate the measurement. The results show that an implementation using printed sensors as a strain gauge works successfully. The resulting challenges, such as measuring strain gradients and printing on curved surfaces, are finally evaluated, and an outlook for further work is given.

“…Epitaxial growth, which is a key element, shapes crystalline structures, leading to the development of micro-LEDs [145]. Processes such as lithography and etching represent the measurements of each micro-LED's size and structure, guaranteeing accuracy in performance.…”

“…Identification of defects and mass transfer challenges has made the mass transfer of Micro LEDs, both in active-matrix and passive-matrix, more complex, thereby requiring testing as well as addressing yield concerns [15]. In this case, the interplay of top-down with bottom-up approaches is a pointer to a future where micro-LED displays will fuse into different applications, leading to a breakaway from traditional visual encounters [145]. This is seen through the coexistence of both methods in making various fabrication techniques that help in advancing micro-LED technology.…”

“…Different layer thickness ranges can be realized with the various printing processes. For example, with the Nano-Jet process, a thinner layer with a thickness of 2 µm can be realized [14]. Furthermore, in printed electronics silver-containing functional materials are established as a source for conductive structures, not coppercontaining pastes [7,15].…”

In this work, on different substrate materials thermally cured polymer thick-film pastes are connected to Surface Mount Technology resistors using a SnBiAg solder alloy. The effect of substrate pre-treatment with atmospheric plasma and thermal cycling on the shear strength of these interconnection is investigated, and the shear forces obtained are graded using MIL-STD 883. In particular, the build-up of solder interconnections on conductive structures made of commercially available copper-containing polymer thick-film pastes and their mechanical characterization is novel. As well as the mechanical characterization of conductive structures, made of polymer thick-film, on plasma-treated substrates and their grading using the MIL-STD 883. In addition, interconnections with silver-containing conductive structures are realized for comparison. Depending on the interconnection system, component mean shear forces of up to 31 N are achieved. While some systems meet the 1.25 x criterion of MIL-STD 883, the majority of the systems investigated do not meet the 1.00 x criterion. Hereby, the adhesion between the conductive structure and the substrate usually fails. Plasma pre-treatment shows an adhesion-increasing effect only for a proportion of substrate materials used, as does thermal aging. Thermal loads can also impair the adhesive strength.
