The #piezoelectric effect happens when certain materials, like quartz, generate electricity when squeezed or stretched. The pressure changes the arrangement of atoms inside, creating an imbalance of electric charges. This imbalance produces an #electric voltage. Conversely, if you apply electricity to these materials, they change shape. This effect allows them to convert mechanical energy to electrical energy and vice versa, making them useful in sensors and electronic devices. | RealPars
