Patent number: 11959876Abstract: 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.Type: GrantFiled: May 7, 2021Date of Patent: April 16, 2024Assignee: Analog Devices International Unlimited CompanyInventors: Alfonso Berduque, Donal McAuliffe, Brendan Cawley, Raymond J. Speer, Youri Ponomarev

Publication number: 20230125558Abstract: Electrochemical sensors (100) include at least two electrodes (110A, HOB), over which an electrolyte (114) is formed. The electrodes are 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 (121) 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.Type: ApplicationFiled: March 15, 2021Publication date: April 27, 2023Inventors: Donal McAuliffe, Rizwan Gill, Alfonso Berduque, Shane Geary, Raymond J. Speer

Patent number: 11536680Abstract: 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.Type: GrantFiled: November 14, 2019Date of Patent: December 27, 2022Assignee: Analog Devices International Unlimited CompanyInventors: Alfonso Berduque, Youri Victorovitch Ponomarev, Brendan Cawley, Donal McAuliffe, Raymond J.

Publication number: 20220163479Abstract: 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.Type: ApplicationFiled: February 11, 2022Publication date: May 26, 2022Inventors: Alfonso Berduque, Youri Victorovitch Ponomarev, Brendan Cawley, Donal McAuliffe, Raymond J.

Publication number: 20220146449Abstract: 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.Type: ApplicationFiled: January 26, 2022Publication date: May 12, 2022Inventors: Alfonso Berduque, Helen Berney, William Allan Lane, Raymond J. Speer, Brendan Cawley, Donal McAuliffe, Patrick Martin McGuinness

Publication number: 20220126300Abstract: The present disclosure relates to a microfabricated thermal platform. The platform is formed over a substrate, which may for example be a silicon wafer, and which may form part of the platform. The substrate is coated in a thermally-insulating material, which may be an organic polymer such, as polyimide or SU8. The thermally-insulating material may have a predetermined thermal conductivity, which is dependent on thickness, geometry and processing. The surface of the thermally-insulating material may include an arrangement of thermal sites, with each site having a reaction plate (or thermal plate) over which chemical reactions may occur. A heating element may be positioned beneath each reaction plate. The thermal platform may have a plurality of such thermal sites arranged over the upper surface of the thermally-insulating material. However, it will be appreciated that in practice, there could be a single thermal site.Type: ApplicationFiled: June 22, 2020Publication date: April 28, 2022Inventors: Christophe Antoine, Helen Berney, Bernard Stenson, Ramji Sitaraman Lakshmana, William Allan Lane, Himanshu Jain, Christina B.
