MICROPUMP DEVICE

摘要

Provided is a micropump device exhibiting good controllability of the quantity of gas generated from a gas generating material and the pumping quantity of a micropump. A micropump device comprises a micropump (10) and a controller (50). The micropump (10) comprises a microchannel (22) that is a liquid channel, a gas generating material (34) for generating gas by receiving irradiation of light and supplying the gas to the microchannel (22), and a light source (42) for irradiating the gas generating material (34) with light (44). The controller (50) supplies the light source (42) with a control pulse signal (CS) for flickering the light source (42) in two-level state by repeating a pulse sequence pattern consisting of a plurality of bits of a fixed number, each bit of which can take two states of a first level for lighting the light source (42) and a second level for unlighting the light source (42).
