Summary: By adding an additional electrode to the printhead to generate an electric field, we were able to use Coulomb force to pull extruded ink in the direction of printing, allowing for faster translational speed, thinner trace widths, and improved deposition on rough surfaces without decreasing build height. This electrostatically-assisted direct ink writing technology has shown orders of magnitude faster speed and the capability to print on super-rough surfaces that were previously impossible.

Summary: To address the issue of microcracks and pores in printed gold nanoparticle films that lead to poor integrity and electrical failure, researchers have used a multifunctional thiol as a cohesion enhancer in the ink, preventing the formation of cracks and pores and improving the cohesion of the gold nanoparticles. The printed gold nanoparticle electrode exhibits stable electrical properties and conductivity even under mechanical deformation and in a salt-rich solution, showing potential for applications in flexible electronics, 3D electronics, bioelectronics, and healthcare devices.

Summary: In this study, flexible micro-supercapacitors (MCSs) based on PEDOT:PSS were fabricated using direct ink writing (DIW) printing. Inks with different PEDOT:PSS concentrations were prepared for DIW printing and their rheological properties and printability were investigated. The optimized PEDOT:PSS ink allowed stable printing and the resulting MCS exhibited high energy storage performance and outstanding cycle stability. The flexibility of the PEDOT:PSS electrode enabled the MCS to maintain its performance under bending stress. Furthermore, the practicality of the system was demonstrated by tailoring the overall operating voltage and output capacitance through printing MCSs connected in series and parallel.

Summary: The purpose of this study was to investigate the possibility of producing structural electronics using the powder bed Binder Jetting (BJ) technique. The BJ ZPrinter 450 printer was successfully adapted for the deposition of silver nanoparticle inks and fabrication of conductive paths. The study tested the influence of different orientations of printed substrates and the number of nanoparticle ink layers on the resistance. The results showed that high-efficiency printed electronics can be fabricated using powder bed techniques, despite the unsuitability of BJ for strain sensor fabrication.
