Sensors allow a MEMS to detect thermal, mechanical, magnetic, electromagnetic, or chemical changes that can be converted by electronic circuitry into usable data, and actuators create physical changes rather than simply measure them. Examples of MEMS Devices. Let's look at an example of the functionality and internal structure of a MEMS device.

Main Structure of MEMS. MEMS is manufactured in a 3D structure, in which an actuator that performs mechanical operations and a sensor that outputs electrical signals from a force applied to an element are formed on a semiconductor substrate. By integrating components that were previously incorporated as separate parts into a chip as micrometer

All MEMs or micro-fabrication device fabrication commences with growth of thin, flat material known as substrate, on which the whole structure is created. While crystalline silicon, owing to its low cost and high availability is the foremost choice for MEMs substrate, other materials like quartz, glass, ceramics, polymers are also used.

MEMS is an acronym that stands for microelectromechanical systems - exceptionally small devices that incorporate mechanical, electrical, and frequently optical components on a single microchip. These devices, despite their micro scale, perform a wide array of functions, from sensing and actuating to data processing and communication.

MEMS micro-electromechanical systems is the technology of microscopic devices incorporating both electronic and moving parts. AlN crystallizes in the wurtzite structure and thus shows pyroelectric and piezoelectric properties enabling sensors, for instance, with sensitivity to normal and shear forces. 15
