Abstract

Various kinds of fluid can be handled and delivered accurately in infinitesimal amounts through microchannels formed in an elastic polymeric substrate by periodically squeezing selective portions of the microchannel using a rotor to apply an external force on the elastic substrate. The delivery rate of the fluid is in the range from pL/sec to mL/sec determined by the rotation speed of the rotor which presses the microchannels and the dimensions of the microchannel. Regardless of physical properties of the fluid to be delivered, various kinds of fluids can be accurately delivered through the microchannels in the desired amount.
