Patent number: 11555725Abstract: A microstructured fluid flow control device includes a substrate with a piezo-actuated first membrane arranged on a first substrate side, and a fluid channel that extends through the substrate between the first substrate side and an opposite second substrate side. In addition, the microstructured fluid flow control device includes a microvalve that extends through the fluid channel and is configured to close the fluid channel in an unactuated state, and a second membrane arranged on the first substrate side and spaced apart from the membrane and arranged between the fluid channel and the first piezo-actuated membrane.
