Summary: 3D laser nanoprinting revolutionizes manufacturing by allowing maskless fabrication of 3D nanostructures at a resolution beyond the optical diffraction limit. It offers printed structures with unique physical, chemical, or mechanical properties not seen at the macro scale. However, its reliance on photopolymerization limits its usability to certain materials and functionalities. The ability to print diverse functional materials and the development of laser nanoprinting techniques beyond photopolymerization open up exciting new applications in nanophotonics and microelectronics.

Summary: Despite the advantages of printed electronic technologies, there are few studies on their technical maturity. Electromigration is an important reliability aspect for printed conductive patterns, and it has been identified as the primary failure mode for interconnect lines in semiconductor-integrated circuits. This study investigates the electromigration characteristics of Ag lines patterned by the electrohydrodynamic printing technique, and finds that ion migration is directed toward the cathode.

Summary: This study presents a simple hydrothermal method to synthesize rGO/Fe2O3 composite, which can be used as the active material in screen-printing functional inks. The functional inks show excellent dispersibility and printability in an EC-ethanol system. By over-printing, performance-controlled screen-printed electrodes were successfully fabricated. In addition, flexible supercapacitors (FSCs) with different printed layers were achieved using rGO/Fe2O3-based printed electrodes, exhibiting remarkable areal capacitances and significant energy densities. The flexibility and stability of the device were also demonstrated. The directly screen-printed integrated rGO/Fe2O3-based printed FSC array provides a stable energy supply and has promising application prospects in wearable energy storage.

Summary: The challenge of high-performance fully printed stretchable OECTs is addressed by developing fully screen-printed stretchable OECTs. Three stretchable functional screen-printing inks are developed, enabling the fabrication of OECTs. The stretchable OECTs show good characteristics and can withstand high strains. An electrochromic smart pixel is demonstrated by connecting a stretchable OECT to a stretchable electrochromic display. The development of screen-printed stretchable electrochemical devices, particularly OECTs, is believed to pave the way for their use in wearable applications and commercial products.

Summary: Aerosol-jet printing (AJP) is an emergent direct-write approach used for rapid and affordable manufacturing of microadditive energy-efficient sensors and printed electronics. AJP can print diverse materials with a wide range of ink viscosities (0.001-1 Pa s) including ceramics, metals, polymers, and biological matter. It enables the conformal printing of complex geometrical designs on nonplanar surfaces with high spatial resolution features (approximately 10 μm) and wide standoff distances (1-11 mm) between the nozzle and substrate.
