Abstract

Inkjet printing technology encompasses the generation, control and deposition of 1-100 picolitre liquid drops. Besides graphic printing applications, new opportunities for inkjet printing are starting to be exploited commercially in the manufacture of high value, high precision products. This talk begins with the principles of inkjet printing process, followed by its electrical and biological applications. I will talk about wearable printed sensor arrays based on organic transistors for healthcare. Next, I will introduce 3D vertically stacked thin film printed transistors and digital circuits as a new route to improve both device performance and transistor density. Finally, I will present some of our recent research on inkjet-printing of cells and hydrogels to make artificial tissues such as skin and lung.
