TLDR
It is shown that the use of substrate surface energy patterning to direct the flow of water-based conducting polymer inkjet droplets enables high-resolution definition of practical channel lengths of 5 micrometers, and high mobilities were achieved.Abstract:
Direct printing of functional electronic materials may provide a new route to low-cost fabrication of integrated circuits. However, to be useful it must allow continuous manufacturing of all circuit components by successive solution deposition and printing steps in the same environment. We demonstrate direct inkjet printing of complete transistor circuits, including via-hole interconnections based on solution-processed polymer conductors, insulators, and self-organizing semiconductors. We show that the use of substrate surface energy patterning to direct the flow of water-based conducting polymer inkjet droplets enables high-resolution definition of practical channel lengths of 5 micrometers. High mobilities of 0.02 square centimeters per volt second and on-off current switching ratios of 10 5 were achieved.read more

The application of organic electrochemical transistors in cell-based biosensors.
TL;DR: Organic thin-fi lm transistors (OTFTs) show many advantages over silicon-based transistors, such as fl exibility, low cost, light weight, easy fabrication, biocompatibility, and environmental friendliness, so it will be of great interest to develop OTFTs to be disposable cell-based biosensors for in vitro or in vivo measurements.
