Microfluidic device with partially restrained element

摘要: A microfluidic flow control device (32) includes a moveable flap (30) capable of intermittently engaging sealing surface(21A). One-way or check valve utility may be provided. Multiple valves coupled to various fluid displacement means provide pumping utility. Devices constructed with stencil layers from materials, including polymeric adhesive tapes, and/or filter materials. Flow devices passively activated by fluidic contents external actuation means.
