Abstract:
1. A fluid sensor comprising: a main body comprising: an underlying substrate and a top plate disposed thereon, a reaction unit including an inner space of the main body, an inlet disposed in a first side of the top plate and fluidly connected to the reaction unit; and an outlet disposed in a second side of the top plate and fluidly connected to the reaction unit, the lower side of the outlet being disposed on the top plate, wherein the reaction unit has a side profile from a vertical cross-section in a direction from the inlet to the outlet that includes a slope at a positive angle (α) to the underlying substrate that is less than a contact angle of the substrate, which tapers the inner space of the reaction unit towards the inlet, and the vertical cross-section of the reaction unit in a direction perpendicular to the direction from the inlet to the outlet, and a horizontal cross-section of the reaction unit, have a shape that is inwardly tapered on both sides, with an inwardly tapered angle (β) that is less than a contact angle of the substrate.
