Method of controlling fluid flow in a microfluidic process |
摘要 |
A method of controlling fluid flow in a microfluidic process includes the step of providing a piezoelectric pumping apparatus (100) in fluid communications with the microfluidic process such as an ink jet printer and the like. The piezoelectric pumping apparatus (100) has a piezoelectric transducer (80) with a functionally gradient piezoelectric element (60) arranged in a fluid containment chamber (120) which fluidically communicates with the microfluidic process. The functionally gradient piezoelectric element (60) responds to a voltage applied by a power source (240) by either expanding to expel fluid from the microfluidic process or contracting to permit fluid to enter the fluid containment chamber (120) and thus the microfluidic process.
