A breath sampling device including a housing having a fluid inlet positioned at a fluid inlet end, a fluid outlet positioned at a fluid outlet end, a fluid channel extending between the fluid inlet and the fluid outlet, and a sensor fluidly coupled to the fluid channel. The sensor is structurally configured to detect a presence of a target gas in a gas sample and a filter assembly fluidly coupled to the fluid channel and positioned between the fluid inlet and the sensor. The filter assembly is structurally configured to absorb heat, water vapor, or a combination thereof.

Breath sampling devices and methods of breath sampling using sensors

Some embodiments include an electrochemical sensor. The electrochemical sensor has a lid element comprising a substrate, multiple electrodes, multiple interior contacts electrically coupled to the multiple electrodes, a base element configured to be coupled to the lid element, and an electrolyte element. The base element includes a sensor cavity, multiple exterior contacts located at an exterior surface of the base element, and multiple signal communication channels comprising multiple signal communication lines, and the electrolyte element is located in the sensor cavity. When the lid element is coupled to the base element, the multiple electrodes are located in the sensor cavity, the multiple electrodes are in electrolytic communication with the electrolyte element, the multiple interior contacts are located in the sensor cavity, and the multiple interior contacts are electrically coupled to the multiple exterior contacts by the multiple signal communication lines. Other embodiments of related sensors and methods are also disclosed.

Electrochemical sensors and packaging and related methods

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.

Printed gas sensor

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.
