This paper presented a valveless micropump driven and sealed by dielectric elastomers (DEs). First, the planar DE actuator was designed and the diaphragm actuating performances were characterized. Then the micropump, containing a chamber and a pair of nozzle/diffuser, was fabricated on SU-8 under exposure to UV-light with a mask. The diaphragm and the SU-8 was sealed by adhesive tape and finally covered...
This paper presents design and numerically study performance of a valveless micropump. The micropump consists of two inlet channels, a pump chamber, and an outlet channel. These components are connected through a specific throat on one planar layer. A side of the pump chamber is enclosed by a vibrating plate which deforms volume of the pump chamber with time, therefore excites fluid from the inlet...
PZT-based micropump is a broadly studied microactuator that could be potentially used for controlling and delivering tiny amounts of fluids as it has simple structure and no internal moving parts. This paper presents a PZT-based micropump which pump fluid via the motion of diaphragm bonded to the piezoelectric element. The mechanical properties of diaphragm driven by input voltages have been analyzed...
With the growing importance of genomics, proteomics, and the discovery of new drugs, controlled transport of fluids in microscale becomes an important and crucial task. Micropump, as an important executive device of microfluidic systems, plays a very important role in micro flow control. They are divided into two types that are pumps with valves and those without them. In general, micropumps with...
