All Screen-Printed Logic Gates Based on Organic Electrochemical Transistors

We report on the fabrication and characterization of entirely screen-printed integrated logic circuits based on organic electrochemical transistors on flexible poly(ethylene terephthalate) (PET) substrates. The transistors are based on poly(3,4-ethylenedioxithiophene) poly(styrenesulfonate) and operate at a voltage of 1.5 V. Together with screen-printed resistors, the printed transistors were used...
