Synergistic Evolution from 2D to 3D Printed Electronics with Versatile Nano-composite Material Systems

Advanced printing techniques with integrated processes for printed electronics on a flat flexible substrate by using direct roll-to-roll transfer of organic functional ink materials have been demonstrated during the tenure of my first Discovery project. Specially, thin film devices including organic field effect transistors, flexible pressure and strain sensors have been investigated as 2D printed electronics. 2D electronic systems are reliable, fast, and potentially cost-effective. But the limitation of these technologies is that they can deposit conductive materials only on flat substrates, though flexible circuits are also possible by later deforming the flat substrate. I believe that 3D printing is natural progression of my 2D printing research for the next five years. 3D printing directly produces devices embedded within 3D structural materials. Especially, I will identify specific research challenges in multi-materials 3D printing and high-resolution 3D printed electronic devices in which functional nano-materials might lead to a step change in technology or performance. Also, addressing such challenges will necessitate the combination of 2D printing and 3D printing technologies.
