Mini electronics in wearables inspired this study. Thus, this work offers a new box-shaped high frequency (7.5 MHz) low aperture 2D phased sparse array ultrasonic transducer …
Piezoelectric materials are broadly used in electromechanical devices including ultrasound transducers, sensors, actuators, resonators, and transformers. Among all the piezoelectric …
Efficient transduction structures and materials have been widely used and developed for several decades. Transduction structures are usually employed at the boundaries of …
