Publication number: 20170131230Abstract: 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.Type: ApplicationFiled: January 23, 2017Publication date: May 11, 2017Applicant: Spec Sensors, LLCInventors: Marc Papageorge, Joseph R.

Patent number: 9213016Abstract: Systems and methods for automated self-compensation are described herein. Accordingly, some embodiments of a method may include measuring a signal from an electrochemical sensor device, where the signal relates to the presence of a predetermined gas, and where the electrochemical sensor device includes a potentiostat, measuring an internal property of the electrochemical sensor device by electronically pinging the potentiostat, and receiving a response from the potentiostat. In some embodiments, the method may include interpreting the response through an associative relationship between the electrochemical sensor device and a data acquisition and calculation module, determining an effect of an environmental factor from the response, compensating for effects of the environmental factor by adjusting the signal from the electrochemical sensor device and outputting the adjusted signal.Type: GrantFiled: August 21, 2014Date of Patent: December 15, 2015Assignee: SPEC Sensors, LLCInventors: Joseph R.
