Publication number: 20150247818Abstract: A sensor for hydrogen in a fluid medium has a chamber for electrolyte with a window which is selectively permeable to hydrogen to allow hydrogen to pass from the fluid medium under test into the electrolyte in the chamber. A plurality of electrodes in contact with the ionic liquid electrolyte are used to observe hydrogen concentration by voltammetry. The electrolyte is an ionic liquid. Applications where such a sensor may be used include a wellbore tool for measuring the content of hydrogen in a subterranean fluid, monitoring of fiber-optic cables for damage by hydrogen, corrosion monitoring, and small-scale process plant where hydrogen is part of a gas stream.Type: ApplicationFiled: October 15, 2013Publication date: September 3, 2015Inventors: Debbie S.

Patent number: 8852983Abstract: A method for fabrication of capacitive environment sensors is provided in which the sensor elements are integrated in a CMOS structure with electronics through the use of complementary metal oxide semiconductor (CMOS) fabrication methods. Also provided are environment sensors fabricated, for example, by the method, and a measurement system using the environment sensors fabricated by the method. The described method includes etching away one of the metal layers in a CMOS chip to create a cavity. This cavity is then filled with an environment-sensitive dielectric material to form a sensing capacitor between plates formed by the metal adhesion layers or an array of contacts from other metal layers of the CMOS structure. This approach provides improved sensing capabilities in a system that is easily manufactured.Type: GrantFiled: May 17, 2013Date of Patent: October 7, 2014Assignee: Carnegie Mellon UniversityInventors: Gary Keith Fedder, Nathan Scott Lazarus
