Inkjet-printed multi-parameter measuring sensor

Abstract

Printed organic sensors on flexible substrates have generated great interest due to their flexibility and low cost manufacturing. Methods such as inkjet printing, screen printing, etching or flexography are among many that have been used for the production process. In this paper, we report the fabrication and characterization of a free-standing, high aspect ratio PEDOT:PSS micro cylinder (20 um in diameter and 1 mm height) multi-parameter sensor printed by an inkjet process. Calibration fabrication and preliminary sensor measurement results from the fabricated sensor will be presented and future applications are discussed.
