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, 反之亦然.
