Piezomaterials are special materials that generate an electric charge when they are mechanically stressed. This property, known as the piezoelectric effect, allows them to convert mechanical energy into electrical energy and vice versa. Common examples of piezomaterials include certain ceramics, crystals, and polymers, which are used in various applications like sensors, actuators, and energy harvesting devices. These materials are widely utilized in technology, such as in microphones and speakers, where they help convert sound waves into electrical signals and back again. Their ability to respond to pressure makes them valuable in industries ranging from healthcare to aerospace, enhancing the functionality of many devices.
