What are MEMS?
MEMS, or Micro-Electro-Mechanical Systems, are tiny integrated devices or systems that combine electrical and mechanical components. These systems are fabricated using microfabrication techniques and typically range in size from micrometers to millimeters. MEMS technology forms the bridge between the emerging fields of
nanotechnology and traditional microscale systems.
How do MEMS relate to Nanotechnology?
MEMS technology often intersects with nanotechnology, particularly in the development of
nanosensors and
nanoactuators. While MEMS devices operate on the microscale, they can incorporate nanoscale elements that enhance their functionality, sensitivity, and performance. For instance, integrating
nanomaterials into MEMS can lead to significant advancements in areas like healthcare, environmental monitoring, and
communications.
