It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini Bharathula explains how piezoelectric materials turn mechanical stress, like pressure, sound waves and other vibrations into electricity, and vice versa.
Lesson by Ashwini Bharathula, animation by Karrot Animation.

  • I used to dig for quartz crystals in Arkansas, and one time had a pair of "pounders" which were too damaged or too cloudy to be worth much so I used this pair to rub together at night to get them to glow! Great fun was had by all.

  • I remember hearing that these are also used for more powerful microscopes. When they have to focus in on an object in the nanoscale, without breaking or dulling the tiny fragile equipment(specifically the cantilever), they need to "inch" one way or another in extremely small units. They run current through piezoelectric materials, which then move the probe part of the microscope up/down or sideways just slightly. I'm not very sure about what I'm saying, does anyone know enough to explain it properly?

    • When a voltage (electric force) is applied to both sides of the crystal, the charged particles that make up the crystal redistribute themselves to align with the electric field (so negative charges move towards the positive side and positive charges move towards the negative side). Depending on the polarity (direction) of this voltage, the crystal will either compress, or expand, this is basically what is shown at 2:45, but in reverse. This small shift in position can be enough to move an object into focus on a microscope. They also use this technique in manufacturing to produce very small objects with precision, such as the billions of transistors inside a computer chip. In this case, they will use many crystals to get the exact positioning required.
