Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the core principle?Integration of micro-scale mechanical components with electronic circuitry
2. What is the dominant forces at microscale?Electrostatic, magnetic, surface tension, and viscosity forces are significant design considerations
3. How small are MEMS?The parts inside a MEMS device are only 1 to 100 micrometers wide, and the whole device is usually between 20 micrometers and 1 millimeter. That’s about the size of a grain of sand or smaller.
4. Why do MEMS need special forces like electrostatic charges?Because MEMS are so small, forces such as electrostatic charges, magnetic forces, surface tension, and viscosity become the main things that move them. These forces are stronger compared to the size of the device.

Micro-Electro-Mechanical Systems (MEMS): Technology integrating microscopic mechanical elements and electronic circuitry, typically on silicon substrates.
Micrometer (µm): A unit of length equal to 10⁻⁶ meters, fundamental to MEMS dimensions.
Actuators: Components that convert energy into mechanical motion, enabling movement in MEMS devices.
Sensors: Devices that detect and respond to physical stimuli from the environment, providing input to MEMS systems.
