Love it or hate it, technology is becoming increasingly intertwined with the outdoors, especially fish finders. Long gone are the days of putting around a lake and looking for clues as to where the ...

Abstract: Piezoelectric Micromachined Ultrasonic Transducers (PMUTs) are widely used in sensing applications, where high-order modes of PMUT can be used to enhance sensing accuracy. However, in ...

Abstract: A new 3-D model of a high-power composite ultrasonic transducer is proposed and evaluated in this article. This transducer comprises two active layers, each with at least two mechanically ...
