Functional Inks for Inkjet Printed Sensors

Recently inkjet printing has emerged as an attractive technology for a variety of scientific applications due to its low-cost and simplicity. Outstanding characteristics of inks based on nanoparticles and carbon nanotubes has made this technology a good choice for various electronic applications such as sensors, transparent electrodes and flexible electronics. The incorporation of metallic, organic and oxide nanoparticles and carbon nanotubes into functional inks is used in order to obtain sensibility to different physical quantities. The present paper focuses on the systematization of commercial and custom-made inks recently developed for desktop inkjet printers.
