Explanation
Not only there is piezoelectricity, but there is also pyroelectricity. As you can guess, it is electricity from when certain materials are heated or cooled.
You will be surprised to learn how often piezoelectricity is used in everyday life. Certain watches take advantage of piezoelectricity. Watches that use quartz are 10 times more accurate than normal watches! In computers, voice recording software use quartz to translate your voice into electrical signals that the computer can read. Do some research on your own and you'll find some more!
Piezoelectricity occurs in crystals (A material in which there is an orderly patterns) where their repeating pattern is non-symmetrical. The particles are isotopes but their charges are canceled out by each other when they are nearby. But whenever you distort their structure their charges go unchecked creating electricity.
Conclusion
Hopefully this presentation sparked your interest in this subject. These concepts sound like science fiction yet are just as apart of our world as sliced bread. It is actually one of many amazing things that make up our world. Enter Reading Rainbow rainbow.
Some Fun Things to Realize
The Inverse Piezoelectric Effect
Piezoelectricity is a fun subject to talk about just because of just how straight from fiction it sounds! Tell one of your friends about how you can generate electricity from quartz and odds are, they won't believe you! This is why I am going to tell you about piezoelectricity. Hopefully, this presentation will jolt your interest. Sorry! Couldn't resist!
We later on discovered that the inverse was true. That electricity flowing through a piezoelectric material cause the material to distort. So obviously scientists called this phenomenon the inverse piezoelectric effect.
In Star Wars, lightsabers are powered by crystals. Lightsabers used be to powered by battery packs in the canon. Hopefully the pieces are forming in your head.
We may figure out how to generate electricity from tears and eggs efficiently and actually apply it.
Maybe we can make a stress ball that creates electricity when you squeeze it.
List of Puns I Could Have Tortured You With That Was Cut off Because There Were Too Many
Resist, power, charge, negative, positive, jolt, buzz, really, there are too many to count. They would short-circuit anyone!

The History
How else could piezoelectricity be used today? Well, scientist actually discovered a chemical in egg shells and tears that exhibits piezoelectricity. Yes, we can have electricity from tears. I'll let you think about that yourself.
A cool thought. If we could get a material to vibrate the right frequency, we can break glass.
There are many things we can do to take advantage of electricity being turned into motion or vice versa.
In the mid-18nth century Carl Linnaeus and Franz Aepinus studied the pyroelectric effect, which we'll cover later on. Using this knowledge they collected, René Just Haüy and Antoine César Becquerel experimented with the relationship between mechanical stress and electric charge, although their experiments were inconclusive. But in 1880, Jacques Curie and Pierre Curie demonstrated the piezoelectric effect and an understanding of what causes it. One year later they deduced that the inverse was true and when they tested it, it was!
