$\textbf{1.)}$Microelectromechanical systems (MEMS, also written as micro-electro-mechanical, MicroElectroMechanical or microelectronic and microelectromechanical systems and the related micromechatronics) is the technology of very small devices; it merges at the nano-scale into nanoelectromechanical systems (NEMS) and nanotechnology.

$\textbf{2.)}$Some common commercial applications of MEMS include:

Inkjet printers, which use piezoelectrics or thermal bubble ejection to deposit ink on paper.

$\textbf{3.)}$Accelerometers in modern cars for a large number of purposes including airbag deployment and electronic stability control.

$\textbf{4.)}$Silicon pressure sensors e.g., car tire pressure sensors, and disposable blood pressure sensors.

$\textbf{5.)}$Displays e.g., the digital micromirror device (DMD) chip in a projector based on DLP technology, which has a surface with several hundred thousand micromirrors or single micro-scanning-mirrors also called microscanners.

$\textbf{6.)}$Optical switching technology, which is used for switching technology and alignment for data communications. Fluid acceleration such as for micro-cooling.
