Laser-based additive nanomanufacturing of functional hybrid materials, structures, and devices

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.
