Abstract: Aspects of the present disclosure include using particles in phase change materials to track temperature change of an object. The particles may be initially disposed at specific locations within the phase change materials. As the phase change materials transition from the solid state to the fluid state, the particles may move from the initial locations to different locations. The change in locations of the particles may be detected magnetically, electrically, optically, and/or visually. Such change may indicate that the object experienced a temperate above at least one phase transition temperature of the phase change materials.

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: 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.

Abstract: A reference electrode with a liquid-impermeable enclosure comprises a chamber for a reference electrolyte. The reference electrode also comprises a first electrode element comprises a reference electrolyte electrode surface arranged to contact a reference electrolyte located within the chamber and a second electrode element is provided at least partially outside the enclosure and comprises a sample electrode surface for contacting a sample. The first and second electrode are electrically connected through the enclosure. Alternatively or additionally, a conductive connecting element defining a part of the enclosure and/or extending through the enclosure electrically connects the first electrode element and the second electrode element.

Abstract: Aspects of this disclosure relate to adjusting fluid flow using magnetically sensitive particles. Fluid can flow through an opening in a container. Magnetically sensitive particles can be confined within the container. A magnetic field can be applied to move the magnetically sensitive particles in the container to adjust flow of the fluid through the opening.

Abstract: Electrochemical sensors can include at least two electrodes, over which an electrolyte is formed. The electrodes can be isolated from one another in order for reduction/oxidation reactions to occur at the electrodes and for an electric current to flow therebetween. The present disclosure describes the use of a barrier in the electrochemical sensor that is configured to isolate electrodes from one another for the purpose of preventing electrode shorting. Additionally, the physical structure of the barrier can also act as a stencil for shaping the electrodes.
