Abstract
A microfluidic system for steering subject materials to a next processing region includes a substrate having at least one embedded gas generator that is activated in response to the result of an initial process, whereby a gas is formed having pressure to steer the subject materials to the next processing region. The gas generator includes resistors that are electrically activated. As current passes through the resistors, thermal energy is released to decompose a selected material from a solid or liquid state to gaseous state. In an alternative embodiment, a gas generator is activated in response to an external control.
