What Is a Piezoelectric Crystal?
A piezoelectric crystal is a unique type of crystal capable of converting mechanical stress into electric charge and vice versa.
Commonly composed of materials such as quartz, ceramics, and polymers, these crystals are integral to the functionality of ultrasonic probes, sensors, actuators, and various medical and optical devices. Their ability to respond to physical pressure by generating an electrical signal forms the basis of their operation. This conversion process, rooted in the crystal’s structured alignment of charges, allows for precise control and measurement in applications ranging from generating ultrasonic waves to powering sensor and actuator systems.
Piezoelectric crystals are celebrated for their high responsiveness, precision, compactness, and efficiency. Ongoing research in areas like nanotechnology and biotechnology continues to expand their applications and promising innovations in piezoelectric technology.
