Printed gas sensor

摘要

A printed gas sensor is disclosed. The sensor may include a porous substrate, an electrode layer, a liquid or gel electrolyte layer, and an encapsulation layer. The electrode layer comprises two or more electrodes that are formed on one side of the porous substrate. The liquid or gel electrolyte layer is in electrolytic contact with the two or more electrodes. The encapsulation layer encapsulates the electrode layer and electrolyte layer thereby forming an integrated structure with the porous substrate.

1. A method of manufacturing a printed gas sensor, the method comprising:
printing two or more porous electrodes onto one side of a partially porous substrate using a metal catalyst ink; curing the partially porous substrate and printed electrodes; bonding an encapsulation layer to the partially porous substrate thereby encapsulating at least a portion of the two or more porous electrodes and forming an electrolyte reservoir; filling the electrolyte reservoir with a liquid or gel electrolyte, wherein the metal catalyst ink comprises 30% PTFE particles, 60% Pt particles and 10% binder.
