ABSTRACT:
A micropump comprises a pump body member for defining a tank chamber holding liquid, a liquid inlet portion, a liquid outlet portion for discharging the liquid medium in the tank chamber, a liquid outlet portion for discharging the liquid medium in the tank chamber, and an actuator for reducing a volume of the tank chamber. The actuator is formed of a liquid-absorptive polymer gel.
