Microactuator

A microactuator is a tiny machine that can move things really small distances. Think of it like a little robot helper that can push or pull things on a very small scale. It can be controlled by electricity, magnets, or even chemicals. Imagine a tiny arm that can pick up a grain of sand or move a cell in your body. That's how small we're talking here. Microactuators are really useful in a lot of different areas, like medicine, computer chips, and robotics. They might be small, but they can do some pretty amazing things!
