摘要： A gas-sensing element includes a gas-sensing surface of transition metal-doped metal oxide semiconductor of a first metal (particularly tin oxide) over a body of the metal oxide semiconductor. The gas-sensing element includes an auxiliary component of: (1) internally-disposed second metal (particularly copper, gold or silver) disposed in the gas-sensing element between the body and the gas-sensing surface, or (2) a metal chalcogenide (particularly sulfide or sulphide) disposed at the gas-sensing surface or internally disposed in the gas-sensing element between the body and the gas-sensing surface that stabilizes the second metal at the gas-sensing surface.

摘要： A combustible gas sensor that includes a reference sensor. The reference sensor includes a first substrate having a first substrate first surface, a first insulating layer disposed on the first substrate first surface, and a first heater at least one of embedded within the first insulating layer and disposed on the first insulating layer. The first substrate is a MEMS substrate.

摘要： A flame detector that includes a spacer, a UV transparent window, and a UV sensing elements. The spacer has a spacer wall that extends along a first axis between a first spacer end and a second spacer end. The UV transparent window is disposed at the first spacer end. The spacer wall and the UV transparent window define a gas space. The UV sensing elements is disposed within the gas space.
