Recently, there has been an increase of research on the portable biomedical
applications such as point-of-care testing (POCT). Consequently, it is required to
develop micropumps which can handle wide variety of fluids as well as are
commercially reasonable, also the whole system needs to be portable. Our pump
satisfies these needs in that the pump is simply actuated by a motor, can transport not
only liquid but also gas, and have many other advantages: flow reversible, multiple
channels, and easy control.
