Simulation of valveless micropump and mode analysis
In this work, a 3-D simulation is performed to study for the solid-fluid coupling effect driven by piezoelectric materials and utilizes asymmetric obstacles to control the flow direction. The result of simulation is also verified. For a micropump, it is crucial to find the optimal working frequency which produce maximum net flow rate. The PZT plate vibrates under the first mode, which is symmet...
متن کاملGlass valveless micropump using electromagnetic actuation
We present a valveless micropump in glass, which is magnetically actuated using the sinusoidal current of an external electromagnet. We employ a powder blasting microerosion process for microstructuring the glass substrates and fusion bonding for assembly of the multi-layered microfluidic chip. The reciprocating type micropump contains two nozzle/diffuser elements and a poly(dimethylsiloxane) m...
متن کاملAn Electromagnetically-Actuated All-PDMS Valveless Micropump for Drug Delivery
This paper presents the fabrication process of a single-chamber planar valveless micropump driven by an external electromagnetic actuator. This micropump features a pair of micro diffuser and nozzle elements used to rectify the fluid flow, and an elastic magnetic membrane used to regulate the pressure in the enclosed fluid chamber. Polydimethylsiloxane (PDMS) is used as the main construction ma...
متن کاملDesign and Simulation of A Piezoelectric Actuated Valveless Micropump
In this work, we design and simulate a valve less, diaphragm-based, piezoelectric micro pump. The piezoelectric actuator is a PZT-5H piezo-disk, the diaphragm is a borosilicate glass plate. All the simulations were made using COMSOL Multiphysics software. First, the piezoelectric actuator and membrane thicknesses were chosen by means of a stationary simulation, using the piezoelectric devices m...
متن کاملSupporting Information Caterpillar Locomotion–inspired Valveless Pneumatic Micropump using Single Teardrop-shaped Elastomeric Membrane
Theoretical Model To design a simple teardrop-shaped membrane, two circles with radii of 2 mm and 0.5 mm, were connected by tangent lines. The two circles were spaced as much as 5 mm apart, from center to center. The shape of the chamber underneath the teardrop-shaped membrane was also the same as that of the membrane. The thickness of the membrane and the height of the chamber were 20 μm and 2...
