# How to squeeze electricity out of crystals

It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity.

Ashwini Bharathula explains how piezoelectric materials turn mechanical stress, like pressure, sound waves and other vibrations into electricity, and vice versa.
