Printed Gas Sensor

摘要

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

1. A printed gas sensor comprising:
a first partially porous substrate comprising one or more gas access regions; one or more printed runners coupled to the first partially porous substrate, wherein the one or more printed runners are non-porous and electrically conductive; an encapsulation layer coupled to the first partially porous substrate and defining an electrolyte cavity positioned within the encapsulation layer; a wick positioned within the electrolyte cavity; one or more printed electrodes printed on the wick and in electrical communication with the one or more printed runners such that the one or more printed runners can transport an electronic signal produced by an electrochemical reaction at the one or more electrodes; and an electrolyte housed within the electrolyte cavity in communication with the electrodes capable of electrolytic communication among the electrodes.
