Utilizing micro-electromechanical systems (MEMS) techniques and a solvent-assisted bonding process, this study fabricates two peristaltic polymethylmethacrylate (PMMA) micropumps. In the first micropump, the actuation chambers are connected via straight microchannels with a uniform width and depth of 500μm and 200μm, respectively, while in the second micropump, the chambers are connected via tapered...
Despite significant efforts to develop micropumps, cumbersome driving equipment means that the design of portable micropumps remains a challenge. This study presents a stand-alone micropump system, which includes a peristaltic micropump based on piezoelectric actuation and a driving circuit. This battery-based driving circuit comprises a 12 V battery, an ATmega 8535 microprocessor, a 12 V-to-180 V...
