FLUID ANALYZING SYSTEM USING FILM-LEVER ACTUATED SWITCHES

WIPO Patent Application WO/2023/035224

A1

A pneumatic-driven fluidic cartridge and systems and methods for operating the same. The cartridge includes a substrate layer, an actuator layer, and an elastic layer. A fluid channel formed in a surface of the substrate layer includes a first chamber and a second chamber separated by a block section. The actuator layer includes a lever positioned to extend across the block section. The elastic layer is positioned between the substrate layer and the actuator layer. The lever applies a force to the elastic layer restricts fluid flow from the first chamber to the second chamber and is configured to bend outwardly opening a channel between the block section and the elastic layer exceeds the first threshold pressure.
