Advances in Piezoelectric/Ultrasonic Sensors and Actuators-2nd Volume

Dear Colleagues,

The piezoelectric/ultrasonic sensor and actuator is an important member of the sensor and actuator family. They utilize the piezoelectric effect and vibration excited through piezoelectric materials to implement sensing and actuating functions. Although they have already been applied in almost every industrial field, advances in piezoelectric materials and in the working principles, fabrication process, structure design, and system integration will definitely further widen the application range of piezoelectric/ultrasonic sensors and actuators. Following 1st Volume on this Topic (https://www.mdpi.com/topics/piezo_ultrasonic_sensors_actuators), we would like to introduce 2nd Volume. This interdisciplinary Topic covers the latest advances in piezoelectric/ultrasonic sensors and actuators, including (but not limited to) the following:

• New piezoelectric materials;
• Development in the working principles of piezoelectric/ultrasonic sensors and actuators;
• Ultrasonic physical/chemical effects;
• Piezoelectric transducers;
