Lab-on-Chip devices are becoming increasingly important as tools for scientific research and applications. These devices are able to miniaturize complex laboratory procedures onto a single chip, allowing for more efficient and accurate results. One of the key challenges in microfluidics is flow control. Precise flow measurement and control is essential in order to ensure that reactions occur as intended and that results are reproducible. Flow control is also necessary in order to prevent clogging, which can be a major problem in microfluidic devices. There are a variety of ways to measure and control flow in microfluidics, and the choice of method depends on the particular application. However, flow measurement and control is an essential part of any Lab-on-Chip system.
