摘要： A gas sensor package is disclosed. The gas sensor package can include a housing defining a first chamber and a second chamber. An electrolyte can be provided in the first chamber. A gas inlet can provide fluid communication between the second chamber and the outside environs. The gas inlet can be configured to permit gas to enter the second chamber from the outside environs. An integrated device die can be mounted to the housing. The integrated device die can comprise a sensing element configured to detect the gas. The integrated device die can have a first side exposed to the first chamber and a second side exposed to the second chamber, with the first side opposite the second side.

摘要： A cap for use with devices, such as sensors. The cap includes protrusions on its underside, to restrict the movement of a liquid or a gel placed under cap. The protrusions may take the form of walls or pillars, depending on the application. As such, the cap retains the liquid or gel in a specified position on the device. For example, an electrochemical sensor may require a liquid electrolyte to remain in place over one or more electrodes. The protrusions may not extend far enough to touch the device, but rather leave a small gap. However, because of the surface tension of the liquid, the liquid generally stays within the protrusions.

摘要： An integrated ion-sensitive probe is provided. In an example, an ion-sensitive probe can include a semiconductor substrate and a first passive electrode attached to the semiconductor substrate. The first passive electrode can be configured to contact a solution and to provide a first electrical voltage as function of a concentration of an ion within the solution. In certain examples, a passive reference electrode can be co-located on the semiconductor substrate. In some examples, processing electronics can be integrated on the semiconductor substrate.
