Currently, printed electronics are manufactured by wet printing technologies such as inkjet and aerosol jet printers, which suffer from major drawbacks, including complex and expensive ink formulations, surfactants/contaminants, limited sources of inks, and the need for high-temperature post-processing. This talk will present a novel additive nanomanufacturing and dry printing technology for multimaterial printing of electronics, sensors, and energy devices. This technology allows in-situ and on-demand generation of various pure nanoparticles (metals, semiconductors, insulators, etc) in the printer head that are then directed toward the printer nozzle and laser-sintered in real-time to form desired patterns and structures layer-by-layer.
Here we have developed a new additive nanomanufacturing (ANM) technique for printing multimaterial structures and patterns on flexible substrates. The ink formulations in the current printed electronics techniques such as inkjet printing and aerosol jet printing is a complex and impure process that limits their applications in printing multifunctional functional devices systems. Also, the required post-treatment processes after every printing make these techniques inefficient and costly. Our ANM technique addressed these challenges by producing various dry and solution-free nanoparticles, which will serve as the building block for printing different multifunctional materials and structures. The printed patterns demonstrate high electrical conductivity and good mechanical reliability, which highlights the promise of this ANM technique dry printing multilateral and flexible hybrid electronics.
