Robust chemiresistor sensor

A chemiresistor sensor probe for detecting the presence of one or more target analytes in the atmosphere of an ambient environment, the probe comprising:

• a molded body comprising a sensing region and a bottom surface opposite of said sensing region;
• a sensor film comprising a cross-linked polymeric matrix located in said sensing region;
• first and second terminals disposed within said body, each of said first and second terminals extending from said sensing region through said bottom surface so as to protrude from said body, each of said first and second terminals comprising an interlocking member disposed between and in direct contact with said sensor film and a respective one of said first and second terminals;
• and
• a molded cap attached to said body and covering said sensor film, said cap comprising at least one aperture which permits the atmosphere of the ambient environment to pass through the cap.

A chemiresistor sensor probe for detecting the presence of one or more target analytes comprising:

• a probe body;
• a sensor film that absorbs the target analytes when the analytes are present mounted at an exterior surface of said probe body;
• and
• a first and a second terminal each having an interlocking device in direct contact with said sensor film.

A chemiresistor sensor system for detecting the presence of one or more analytes comprising:

• a probe including a first electrode and a second electrode each having a conductive interlocking device in direct contact with a sensor film, said probe operable to generate a first output indicative of the absence or presence of the analytes in the environment;
• a control unit in electrical communication with said first and second electrodes, said control unit operable to receive said first output from said probe and generate a signal corresponding to said first output;
• and
• a user interface in communication with said control unit, said user interface operable to receive said signal from said control unit and generate a second output corresponding to the absence or presence of analytes in the environment.
