Miniaturization

Definition

Miniaturization refers to the process of reducing the size of devices, components, or systems while maintaining or enhancing their functionality and efficiency. This concept is critical in fields like engineering and manufacturing, where smaller designs often lead to improved performance, reduced resource consumption, and greater integration of technologies, ultimately resulting in more compact and efficient processes.
