Abstract: Electrochemical sensors typically include capillaries or openings in a substrate which allow the gas present in the environment to make its way into the sensor. The present disclosure proposes the use of a hydrophobic layer, coating or surface in various arrangements around these openings in order to help prevent or restrict electrolyte leaving the sensor and also prevent moisture or other liquids entering the sensor. In some such electrochemical sensors, the hydrophobic layer acts to prevent or restrict electrolyte from drying out or leaving the sensor. In other such electrochemical sensors, there is a porous electrode and a liquid electrolyte, with the hydrophobic layer repelling the electrolyte from passing through the electrode and out of the electrochemical sensor. In yet other such electrochemical sensors, the sensor is manufactured forming at least one layer of hydrophobic material in order to help prevent or restrict electrolyte from drying out or from leaving the sensor, and also prevent or restrict moisture or other liquids entering the sensor.

Abstract: An electrochemical sensor is provided which may be formed using micromachining techniques commonly used in the manufacture of integrated circuits. This is achieved by forming microcapillaries in a silicon substrate and forming an opening in an insulating layer to allow environmental gases to reach through to the top side of the substrate. A porous electrode is printed on the top side of the insulating layer such that the electrode is formed in the opening in the insulating layer. The sensor also comprises at least one additional electrode. The electrolyte is then formed on top of the electrodes. A cap is formed over the electrodes and electrolyte. This arrangement may easily be produced using micromachining techniques.

Abstract: 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.

Abstract: Electrochemical sensors include a housing within which an electrolyte is provided over the electrodes. The housing includes an active region, which is the area around the electrodes in which the electrolyte must be positioned to ensure correct operation of the device. The inner walls, base and ceiling of the housing are coated in either hydrophobic or hydrophilic materials, or both, so as to encourage the electrolyte to take a position over the active region, which is defined by the position of the electrodes. In some electrochemical sensors, a combination of hydrophobic and hydrophilic materials is used and the materials can be arranged in a pattern, which encourages the electrolyte to take a position over the active region.
