Microelectromechanical Systems (MEMS) - Nanotechnology

What are Microelectromechanical Systems (MEMS)?

Microelectromechanical Systems (MEMS) are miniaturized mechanical and electro-mechanical elements that are made using microfabrication techniques. These can range from simple structures without moving elements to complex systems with multiple moving parts performing various functions. MEMS typically integrate sensors, actuators, and electronic components on a single chip, enabling a wide array of applications from automotive to biomedical fields.

How Do MEMS Relate to Nanotechnology?

Nanotechnology plays a significant role in advancing MEMS technology by enabling the fabrication of even smaller and more efficient components. While MEMS operate at the microscale, many of the materials and techniques used in their creation are derived from nanotechnology. This includes the use of nanoscale materials for improved performance and reliability, as well as nanofabrication techniques that allow for precise control over the dimensions and properties of the MEMS components.
