Paper Abstract

As a critical research area, micropump has extensively emerged for many electronics and biological applications, especially for drug delivery. The actuating diaphragm, a key component of micropump, plays an important role in pumping-system. IPMC is a promising material candidate for micropump actuating diaphragm since it can be operated with low input voltages and can produce a large stroke by appropriate structural design. In this paper, we introduce a kind of petal-IPMC diaphragm obtained by mechanical cutting into micropump. In this work, inner petal-shaped IPMC actuator with the petal number of 8 was employed. We fabricate inner petal-shaped IPMC actuator with the dimension of 1.0cm, 1.5cm and 2.5cm in diameter and measure their electromechanical responses under 1-3V DC and AC voltage. After that, we assemble the micropump by a silicone material and the petal-shaped IPMC actuator above and the experimental characterizations of the micropump were performed. Experimental results show that, inner petal-shaped IPMC actuator with a diameter of 25mm produce a maximum deformation up to 0.7mm in central point. For the micropump prototype integrated with inner petal-shaped IPMC actuator with a diameter of 15mm, the flow 162μL/min to 1611μL/min can be obtained in 1Hz sine voltage input by changing the voltage amplitude from 0.5V to 3V, and the back pressure on the micropump can be as high as 71mm-H2O.
