Piezoelectricity: Why quartz ticks Subject : Science and Tech Section: Msc Introduction  Piezoelectricity is a remarkable phenomenon whereby some materials – including quartz, ceramics such as lead zirconate titanate (PZT), and even certain biological substances like  bone and the tendons – can generate an electric charge in response to mechanical stress.  What is the Piezoelectric Effect? The piezoelectric effect is a phenomenon in which certain materials produce an electrical charge in response to mechanical stress or pressure. This effect occurs when the […]
