Tiny battery with a positive charge on one face and a negative charge In practice, the crystal becomes a kind of Piezoelectricity (also called the piezoelectric effect) is theĪppearance of an electrical potential (a voltage, in other words)Īcross the sides of a crystal when you subject it to mechanical That's pretty much piezoelectricity in a nutshellīut, for the sake of science, let's have a formal definition: Through the same crystals, they 'squeeze themselves' by vibratingīack and forth. The reverse is usually true as well: if you pass electricity Squeeze certain crystals (such as quartz) and you can make Find out more What is piezoelectricity?.Energy harvesting with piezoelectricity?.Photo by courtesy of NASA Langley Research Center (NASA-LaRC).

Is much simpler than it sounds: it just means using crystals to convert mechanical energy intoĮlectricity or vice-versa. Piezoelectricity (literally, 'pressing electricity') Would have been using piezoelectricity to 'read' the sounds from If you're a bit ofĪn audiophile and like listening to music on vinyl, your gramophone Piezoelectricity to turn the sound energy in your voice intoĮlectrical signals your computer could interpret. Writing a letter or an essay on your computer with the help of Piezoelectricity is what helps it keep regular time. You've probably used piezoelectricity (pronounced ' pee-ay-zo-electricity')
