High Sound Pressure PMUT Based on Sputtered KNN for Haptic, Speakers, and Rangefinders
Ultrasonic transducers have been widely used in object detection, non-destructive testing (NDT), biomedical imaging, and therapy. Compared to bulk ultrasonic transducers, piezoelectric micromachined ultrasonic transducers (PMUTs) with a small footprint have advantages such as low power consumption and wide bandwidth, making them suitable for various applications in consumer electronics and the Internet of Things (IoT), … Read more
