Fig. 2. Flow rate characterization for eight designs of the single-stroke micropump (SSμP).

Fig. 2

Three-element serial SSμP (a) design schematic and (b) flow rate measurement in (i) forward and (ii) backward pumping mode. Measurements were taken in the sequence of ascending frequency (solid lines) initially followed by a descending sequence (dotted lines) to test membrane hysteresis. Four-element parallel SSμP (c) design schematic and (d) flow rate measurement.
