Monolithic integration

Definition

Monolithic integration is the process of combining multiple electronic components, such as sensors, transistors, and circuits, onto a single semiconductor substrate. This technique enhances performance and reduces the size and weight of wearable electronic devices by eliminating the need for separate components and interconnections. By integrating components at a microscopic level, it allows for improved functionality, energy efficiency, and reliability in wearable technologies.
