A novel selective metallization process to fabricate the fine conductive line based on drop-on-demand (DoD) inkjet printing was studied. Direct inkjet printing is an alternative and costeffective technology for patterning and fabricating objects directly from design or image files without making masks and patterns. The conductive ink used in this experiment consists of 1 to 50 nm silver particles that are homogeneously suspended in an organic carrier. A piezo-electric inkjet print head driven by a bipolar voltage signal is used to dispense 20-40μm diameter droplets. Repeatability of circuitry fabrication is closely related to the formation of steady, satellite-free droplets. Therefore, the ability to form small and stable droplets with a same size, constant velocity and the correct flight angle must be taken into consideration for fine and precise conductive lines. In this study, parameters affecting the pattern formation such as drop formation, drop placement accuracy and velocity deviation between each nozzle have been investigated. As a result, direct inkjet patterning systems equipped with several functioning modules and fine metallic patterns have been developed.

In this work we present the development of a low-cost humidity and temperature sensing platform on paper by inkjet printing, using a commercial AgNPs conductive ink. The humidity sensing module was capable of measuring relative humidity in the range of 0–90%rH, exhibiting linear response with minimal memory effect when returning to 0%rH baseline signal while the temperature sensor performed linearly as well in the range of 25–75°C. Process repeatability has been verified by electrical and optical characterization. Mechanical bending results highlight the platform’s capability to serve as an easy to install, flexible multi-parametric sensing platform.

Abstract This present paper describes some test results about fabrication of micro/nano-structure for MEMS using printing techniques of metal and nanoparticle thin films. Transfer-printing of a bi-layered film of graphene oxide (GO) and Au is processed on a PET substrate. Nano-particles of GO are cast on a micro-ridged poly-dimethyl-siloxane stamp that is previously coated with Au by solution casting. The layer of GO nanoparticles functions as a reinforcing material to strengthen the layered film while the Au thin-film is a matrix that links the GO nanoparticles. The thickness of GO nanoparticles varies with concentration of GO suspension. In the case of thicker coating of GO with an average thickness of 13 nm, the transfer-printing makes the GO/Au bi-layered film form into 50-μm-wide two-dimensional line patterns on the PET substrate. Additionally, transfer-printing of another bi-layered film with a 128 nm thickness fabricates a three-dimensional microstructure of a rectangular-corrugated film on the PET substrate because the entire bi-layered film is transferred from the stamp. The modulus of transfer-printed GO/Au bi-layered film is investigated by a simple bending tests using AFM cantilever. FEM analysis of the bending test results indicates that the mechanical modulus of the GO/Au film is not less than 120 GPa, and this significantly exceeds that of the Au film by itself. The present study also fabricated a capacitive MEMS sensor by a combination of transfer-printing and inkjet printing. Inkjet printing makes GO nanoparticles on the 100-μm-wide comb-like microelectrode, which is previously fabricated by transfer-printing of Au thin film. The fabricated MEMS sensor successfully shows its change of capacitance with relative humidity in the range of 40% to 80%. These results demonstrate that the printing of Au and GO nanoparticles is effective for MEMS fabrication.

Noble metal nanoparticles have special properties in optical, electronic, and physical chemistry due to their high surface area and volume. With the development of electronic printing technology, inkjet printing has gradually replaced traditional spin coating and blade coating, since it leads to more material savings and a faster batch production, and the pattern can be easily designed by a computer. In this study, Ag nanoparticles were prepared by a chemical reduction method. Non-toxic, environment-friendly agents were selected to fabricate a single-shape, uniform-size, crystal-form, and monodisperse product. The effects of the reducing agent ratio and the stabilizer ratio on the size, shape, and stability of the nanoparticles are discussed. The silver nanoparticles were characterized by an ultraviolet-visible spectrophotometer (UV-vis) and a transmission electron microscope (TEM). In addition, in order to prepare conductive ink that can stably disperse for a long time and that can be applied to inkjet printing on a PET flexible substrate at a lower sintering temperature, a sintering agent and a commercial surfactant were added. The experimental results show that the best addition ratio of the precursor to the reducing agent and the stabilizer is 1:6:1. The conductive silver ink was printed and treated by a70 mM NaCl solution, and the electric resistivity was 5.17×10−4 Ω· cm.

Abstract Micro-sized lines were inkjet printed on glass fibre fabrics using different droplet spacing. A conductive ink containing silver nanoparticles was used in this study. Glass fibre fabrics were differently pre-treated to avoid spontaneous spreading of the ink dispersion. The sample topography was examined using scanning electron, optical and confocal microscopy with a chromatic sensor. Printability conditions were discussed based on the results of topographic characterization and wettability measurements.
