Preliminary control integration Membrane(located behind the cross-section) Substrate (pyrex) Fluid control Membrane Microchannel (test fluid) Hidden fluid control
Control Channels vs. Independent On/Off valves Control Channels (yellow) On/Off valves
Control Flow Channels and Piezoelectric Challenges One control channel will manipulate 3 of the microchannels, giving us less control. Unless we develop a logic system. The membrane will need to be thin, making it difficult to peel away the layer from the mold. The electrical interconnects will be throughout the device. Will there be a way to integrate metal and polymer. If we have a peel and layer process, how will we insert the piezoelectric (or similar material) into the device?
