Microsystems refer to small-scale devices or systems that typically integrate various components such as sensors, actuators, and control electronics on a single chip or substrate. These systems are designed to perform specific functions in a compact and efficient manner. They are commonly used in applications such as biomedical devices, environmental monitoring, and consumer electronics. The field of microsystems encompasses a wide range of technologies, including MEMS (Microelectromechanical Systems) and NEMS (Nanoelectromechanical Systems), and involves interdisciplinary research that combines expertise in materials science, physics, engineering, and biology. The development of microsystems has led to advancements in miniaturization, sensor technology, and system integration, making them an important area of research in the field of engineering and technology.
