Introduction to microfluidics

Abstract

Utilization of MEMS devices that employ fluids offers many advantages over macroscale devices, including enhanced portability and performance, as well as allowing for increased integration and automation. The array of microscale devices that incorporate fluids is large, and includes inkjet printer heads, devices used for DNA amplification, a variety of sensors, and a number of emerging technologies such as the use of microneedles for drug delivery. The use of fluids at the microscale is also becoming increasingly important in thermal management, particularly through the use of microfluidic devices to cool electronic components. Power generation via microscale turbomachinery and even microrocket engines are currently under development as well. Figure 12.1 gives yet another application, the use of controlled fluid flow to grow crystals.
