Other Piezoelectric Devices

• Piezoelectric Transformers: Convert voltage using mechanical vibration instead of magnetic fields.
• Ultrasonic Motors: Use high-frequency vibrations to produce precise motion; common in camera lenses.
• Piezoelectric Sensors: Detect pressure, force, or acceleration in industrial and automotive systems.
• Piezoelectric Actuators: Provide nanometer-level positioning in precision equipment (e.g., AFM).
• Energy Harvesters: Capture ambient vibrations to power low-energy electronics.
• Buzzers & Speakers: Generate sound via piezoelectric element vibration.
• Medical Ultrasound Transducers: Emit and receive ultrasonic waves for imaging.
• Ignition Systems: Used in lighters and stoves to generate sparks.
