Patent number: 9513242Abstract: A humidity sensor may include a first substrate having a recess formed in a first side, a second substrate and an insulating layer supported by the second substrate. The second substrate and the insulating layer may be supported by the first side of the first substrate and extend over the recess to form a diaphragm with the insulating layer facing the recess. The diaphragm may be at least partially thermally isolated from a remainder of the second substrate. A resistive heater element may be supported by the diaphragm. A pair of sensing electrodes are electrically separated from each other and supported by the diaphragm. A sensing material is disposed over the pair of sensing electrodes, wherein an electrical property of the sensing material changes in response to a change in moisture content of the sensing material.Type: GrantFiled: September 12, 2014Date of Patent: December 6, 2016Assignee: Honeywell International Inc.Inventors: Scott E.

Patent number: 9470593Abstract: A pressure sensor includes a pressure sensing element and a top cap. The pressure sensing element includes a bonded wafer substrate having a buried sealed cavity. A wall of the buried sealed cavity forms a sensing diaphragm. One or more sense elements may be supported by the sensing diaphragm and one or more bond pads are supported by the upper side of the bonded wafer substrate. Each of the bond pads may be positioned adjacent to the sensing diaphragm and electrically connected to one or more of the sense elements. The top cap may be secured to the upper side of the bonded wafer substrate such that an aperture in the top cap facilitates passage of a media in a downward direction to the sensing diaphragm. The top cap may be configured to isolate the bond pads from the media.Type: GrantFiled: September 12, 2013Date of Patent: October 18, 2016Assignee: Honeywell International Inc.Inventors: Richard A.

Patent number: 9267857Abstract: A pressure sensor having a diaphragm having a boss with a pattern. The diaphragm having a boss may be regarded as a bossed diaphragm. The bossed diaphragm may have higher sensitivity than a flat plate diaphragm having the same area as the bossed diaphragm. The bossed diaphragm may incorporate a simple cross pattern that can further improve the sensitivity and linearity of a pressure response of the diaphragm at low pressures. Reduction of sharp edges and corners of the boss and its legs around the periphery of the diaphragm may reduce high stress points and thus increase the burst pressure rating of the bossed diaphragm.Type: GrantFiled: November 17, 2014Date of Patent: February 23, 2016Assignee: Honeywell International Inc.Inventors: Carl Stewart, Richard Davis, Gilberto Morales

Patent number: 9156676Abstract: A sensor assembly includes a first wafer having a cavity formed therein and a second wafer bonded relative to the first wafer to form a diaphragm over the cavity. A trench is formed in the second wafer in or around the diaphragm and the trench may be filled with an isolating material to help thermally and/or electrically isolate the diaphragm. The diaphragm may support one or more sense elements. The sensor assembly may be used a flow sensor, a pressure sensor, a temperature sensor, and/or any other suitable sensor, as desired.Type: GrantFiled: April 9, 2013Date of Patent: October 13, 2015Assignee: Honeywell International Inc.Inventors: Carl Stewart, Scott E.
