Abstract

This review paper provides a detailed analysis of the fundamental concepts of oscillating feedback micromixers (OFMs) and describes the primary mechanisms that control their operation, such as feedback loops, oscillation creation, and their impact on fluid dynamics at the microscale. The discovery of new materials, innovative design techniques, and integration strategies that have improved the functioning and efficiency of OFMs in a variety of microfluidic applications are among the notable advancements in the sector that are also highlighted. The report also discusses current challenges for researchers, such as optimizing mixing efficiency, cutting down on energy use, and addressing scaling issues in commercial applications. The potential for integration with other microfluidic technologies, the exploration of innovative actuation methods, and the growing application of OFMs in cutting-edge fields including drug delivery systems, lab-on-a-chip devices, and point-of-care diagnostics are all covered in the review's conclusion. Because of these insights, the paper provides a comprehensive understanding of the state of OFM technology today and its potential in the future.
