“…Serving as core architectural elements, MEMS actuators have emerged as a promising technology that plays a vital role in enabling a wide range of biomedical devices. Among existing MEMS actuators, those with thermoresponsive [22], electromagnetic [23], piezoelectric [24], thermopneumatic [25], and pneumatic [26] mechanisms have been some of the representative types widely used for biomedical applications. Each of these actuator types possesses attractive features.…”

Micro-electromechanical-system (MEMS) based actuators, which transduce certain domains of energy into mechanical movements in the microscopic scale, are increasingly contributing to the areas of biomedical engineering and healthcare applications. They are enabling new functionalities in biomedical devices through their unique miniaturized features. An effective selection of a particular actuator, among a wide range of actuator types available in the MEMS field, needs to be made through the assessment of many factors involved in both the actuator itself and the target application. This paper presents an overview of the state-of-the-art MEMS actuators that have been developed for biomedical applications. The actuation methods, working principle, and imperative features of these actuators are discussed along with their specific applications. An emphasis of this review is placed on temperature-responsive, electromagnetic, piezoelectric, and fluid-driven actuators towards various application areas including lab-on-a-chip, drug delivery systems, cardiac devices and surgical tools. It also highlights the key issues of MEMS actuators in light of biomedical applications.

Fluid–structure interaction (FSI) is a nonlinear multiphysics phenomenon that describes the interactions between incompressible fluid flows and immersed structures, making it invaluable to biomedical research. In this work, the common FSI methodologies in biomedical research were systematically summarized and classified into three groups based on FSI interfaces: fluid–channel interfaces, fluid–particle interfaces, and multi-interface interactions. A discussion of the role of the numerical FSI methods was also made, outlining its indispensable advantage in handling complex geometries, boundary conditions, and thus FSI interfaces. The applications of these methods are discussed in terms of blood vessel-related applications, drug-delivering micropumps, particle dynamics/cell sorting, and particle deformation and rapture. The development progress, current advances, and prospects of FSI's future application in biomedical research were illustrated. It was concluded that with the advances in computation technologies, the rapidly developing FSI methods can achieve state-of-the-art level details, helping to improve our understanding of various biomedical-related problems and the use of FSI techniques in biomedical research is likely to continue to grow.
