Design, fabrication, and modeling of the pump

Trilayer PPy petals were cut from a sample fabricated using the procedure described in Section 5.2. The body of the micropump, including its flap check valves, was fabricated with polydimethylsiloxane (PDMS) using MEMS processes [Fang and Tan (2010)]. Fig. 9.23 shows the assembled

Under an actuation voltage of 4 V, the maximum flow of the PPy petals-actuated pump was 1260 pL/min, achieved at about 0.5 Hz. The corresponding power consumption was about 310 mW. In comparison, the PPy-based diaphragm pump reported by Kim et al. [Kim et al. (2008)] had
