Electronic Ink Formulation for Drop-on-Demand (DoD) Inkjet Printing Fabrication Process

Inks for manufacturing of inkjet-printed radio frequency (RF) electronics on cellulose-based and synthetic paper substrates are introduced in this paper. A general electronic ink formulation procedure as well as formulated electronic inks, such as SU-8 and PVP inks, are discussed in this paper. The reported technology could potentially set up the foundation for the first truly “green” low-cost scalable wireless topologies for autonomous Internet-of-Things and “smart skin” applications.
