Harnessing Crystal Power: How Pressing Sugar Crystals Can Generate Electricity ⚡

View full lesson: <br /><br />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. <br /><br />Lesson by Ashwini Bharathula, animation by Karrot Animation.
