This paper presents the design,fabrication,and experimental characterization of a peristaltic micropump.The micropump is composed of two layers fabricated from Polydimethylsiloxane(PDMS) material.The first layer has a rectangular channel and two valve seals.Three rectangular mini lightweight piezo-composite actuators are integrated in the second layer,and used as actuation parts.Two layers are bonded,and covered by two Polymethyl Methacrylate(PMMA) plates,which help increase the stiffness of the micropump.A maximum flow rate of 900 μL·min-1 and a maximum backpressure of 1.8 kPa are recorded when water is used as pump liquid.We measured the power consumption of the micropump.The micropump is found to be a prom-ising candidate for bio-medical application due to its bio-compatibility,portability,bidirectionality,and simple effective design.

Two layers are bonded and covered by two Polymethyl Methacrylate (PMMA) plates, which help increase the stiffness of the micropump. A maximum flow rate of 900 μL · min -1 and a maximum backpressure of 1.8 kPa are recorded when water is used as pump liquid. We measured the power consumption of the micropump. The micropump is found to be prom-isning candidate for bio-medical application due to its bio-compatibility, portability , bidirectionality, and simple effective design.
