Abstract: A vehicle seat that includes: at least one support element defining a cavity, an air pump, and at least one olfactory diffuser arranged in the cavity and fluidly connected to the air pump, the olfactory diffuser having an outer casing defining an inner volume, the outer casing defining an air inlet and an air outlet, the olfactory diffuser further having at least one olfactory substance carrier arranged in the inner volume defined by the outer casing. The air pump causes the circulation of a flow of air through the inner volume from the air inlet to the air outlet toward the outside of the cavity.

Abstract: A process for fabricating a detecting device includes producing a getter pad based on amorphous carbon resting on a mineral sacrificial layer that covers a thermal detector and producing a thin encapsulating layer that rests on the mineral sacrificial layer and that covers an upper face and sidewalls of the getter pad. The mineral sacrificial layer is removed via a first chemical etch, and a protective segment of the getter pad is removed via a second chemical etch.
