Abstract
Microfluidic devices with peristaltic pumps and valves have been fabricated based on the thermal plastic materials by using the rapid hot-embossing method. Two types of configurations of the microfluidic devices are presented. Both of them are based on the use of membrane layer made of thermoplastic elastomer materials. The frequency and pressure dependence of the pumping rate are studied and compared among the conventional, S-shape and U-shape designs. The maximum flow rate of the conventional peristaltic design is about 2 times of that of the U-shape design with the identical microfluidic channel under the same operation pressure. The advantage of S-shape and U-shape peristaltic design over the conventional design is that the number of electromagnetic valves used in the pneumatic manifold can be reduced. A simple rotary microfluidic device with peristaltic pumps was fabricated and the microvalving, micropumping and micromixing operations have been demonstrated.
