  • Normally closed valve for microfluidic components of a polymeric layer system and method
    Patent number: 9664304
    Abstract: A normally closed valve for microfluidic components includes a polymer substrate and a polymer membrane film arranged on the polymer substrate. The polymer substrate has a first chamber, a second chamber, and a fluidic barrier element configured to separate the first chamber from the second chamber. The first chamber is fluidically coupled to the second chamber by the polymer membrane film, and, in an initial configuration, a connection of the polymer membrane film to the fluidic barrier element prevents a fluidic communication of the first chamber to the second chamber. The first chamber is at least partially filled with a substance in the initial configuration, and a transfer of the substance from the first chamber into the second chamber takes place by applying a pressure to the substance. The pressure is chosen to be great enough to disconnect the connection of the polymer membrane film to the fluidic barrier element.
