How PZT sensors detection external impacts?
When a piezoelectric material is subjected to deformation, it gives off a small but measurable amount of electricity. Because of this property, these materials are widely used as sensors and actuators such as ultrasonic transducers, electronic filters and resonators, delay lines, and accelerometers. Devices based on piezoelectric effects have several key technical advantages, including reduced size, greater efficiency, and ease of fabrication. As a result, piezoelectric devices have dominated the field for these applications. The external impact detection by PZT sensor is illustrated in the followingFigure.
