Design, Fabrication and Testing Highly Sensitive Single Element Doppler Transducers
Bolstad, Per Kristian; Hoff, Lars; Torp, Hans; Johansen, Tonni Franke (Journal article; Peer reviewed, 2018)Three common piezoelectric materials have been studied for use in pulsed wave Doppler ultrasound, where high sensitivity is required, while bandwidth is less important. A large transducer aperture, 80 mm 2 , results in a ... -
Finite Element Modeling of Heat Generation in 1-3 Piezocomposite Transducers for Underwater Ultrasonic Applications
Myrstuen, Lars Erik (Master thesis, 2018)Today, piezoelectric ultrasound transducers are used extensively for underwater applications such as sonar. In such transducers, operating in thickness mode, the active part is often a 1-3 piezocomposite, usually made of ...
