Micromanufacturing is an interdisciplinary research field and technological approach focused on the design, fabrication, and assembly of structures, devices, and systems with critical dimensions typically ranging from micrometers to sub-micrometers. It investigates novel materials, processes, and methodologies to achieve high precision, complex geometries, and functional integration at this scale. This field is significant for enabling the development of microelectromechanical systems (MEMS), microfluidic devices, micro-optics, and other miniaturized components essential for advanced technologies in electronics, healthcare, aerospace, and beyond.
