Piezoelectricity

Piezoelectricity is the ability of certain materials to generate an electric charge when they are mechanically stressed or deformed. This means that when these materials, like quartz or certain ceramics, are squeezed, twisted, or bent, they produce a small voltage. This property is used in various applications, such as microphones, speakers, and sensors, where mechanical energy needs to be converted into electrical energy or vice versa. Essentially, piezoelectric materials bridge the gap between physical movement and electrical signals, making them valuable in technology and engineering.
