Abstract
This study is to fabricate a valveless micropump by using PMMA
materials, and the micropump uses piezoelectric disk to drive the fulid,
and it uses diffuser/nozzle principle to get the flow rate. In diffuser/nozzle
design, the micropump compares different length and angle with the other
one. It may be seen that on the same angle the maximum flow rates of the
different length single micropumps are the same, but the trend of the
shorter length is smoother and sensitivity is lower near the maximum
flow rate. On the different angles of 4.6°and 9.8°, it could be seen that
the performance and the maximum flow rate of 9.8° is better. In addition,
in the study it also analyse flow rate of the dual micropump in series. It
could be seen that fixing one chamber and driving the other one is
promoting the flow rate. it also fabricate dual chamber micropump in
series to compare the flow rate with single chamber micropump in phase
and in anti-phase, and it could be seen that at the phase angle of 90°, a
three-fold increase of flow rate is relative to that of a sinle chamber
operation.
