What is a MEMS (Micro-Electromechanical System)?

A MEMS is like a tiny robot that lives inside something you use every day, like your phone or a toy.

Imagine you have a little box that can move parts inside it when you press a button. That's kind of what a MEMS does, but even tinier! It uses electricity and small moving pieces to do things like sense motion, measure how much something weighs, or even make sounds.

How It Works

Think of it like a mini version of a seesaw, when one side goes up, the other goes down. In a MEMS, tiny parts move in response to changes around them, just like that seesaw.

Where You Find Them

You might not notice them, but MEMS are inside your phone’s motion sensor, your smartwatch, or even your toy car! They help those devices know when you're moving, shaking, or pressing buttons, all without needing big parts or complicated machines.
