  • Topography layer
    Patent number: 7585052
    Abstract: An inkjet print-head is formed by selectively disposing a first layer on a substrate. The first layer and the substrate form a topography. A second layer is selectively disposed over the substrate and the first layer. A third layer is disposed over the second layer. The second layer selectively disposed over the substrate and the first layer reduces a surface topography of the third layer.

  • Methods and devices for modulating fluid flow in a micro-fluidic channel
    Publication number: 20060243934
    Abstract: The present invention is drawn to a method for modulating fluid flow in a micro-fluidic channel, comprising the step of applying heat to a valve of a micro-fluidic channeling device. The valve can include an elastically resilient portion having a first configuration prior to application of heat and a second configuration after application of heat. In one aspect, the first configuration provides an open valve configuration and the second configuration provides a closed valve configuration. In another aspect, the first configuration provides a closed valve configuration and the second configuration provides an open valve configuration.
