The Invisible Revolution in Your Pocket

Imagine a technology so small it could fit on the tip of your finger, yet powerful enough to control aeroplanes, save lives, and make your smartphone "smart". This is MEMS (Micro-Electro-Mechanical Systems) - the hidden technology that's revolutionising our world.

What Exactly is MEMS?

MEMS technology is essentially a miniature version of larger mechanical systems, but at a microscopic scale. Think of it as creating tiny machines, some smaller than a human hair, that can sense, think, and act.

How small are we talking?

• Typical MEMS devices range from 20 micrometres to 1 millimetre

• That's smaller than the diameter of a human hair (about 75 micrometres)

• Some components are so small they're invisible to the naked eye
