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.
