Microengineering is a field of engineering that focuses on the design and fabrication of very small structures and devices, often at the micrometer or nanometer scale. This discipline combines principles from various areas, including mechanical engineering, electrical engineering, and materials science, to create components that can be used in applications like medical devices, sensors, and microelectronics. The techniques used in microengineering often involve advanced methods such as photolithography and etching to create intricate patterns on materials. These tiny structures can lead to innovations in technology, enabling the development of more efficient microprocessors and biomedical implants, which can significantly improve performance and functionality in various industries.
