Characterization of Layers with Metal-Coated Polymer Spheres for use in Ultrasound Transducers
Nicolaisen, Anette Sollien (Master thesis, 2021)The properties of materials used in ultrasound transducers affect the properties of the finished transducer, making it important to characterize the acoustic properties of these materials. The study in this thesis is ... -
Evaluation and simulation of LiNbO3 (Lithium Niobate) piezocomposite ultrasound transducer with center frequency of 3MHz.
Malekianarani, Bahareh (Master thesis, 2024)An ultrasound transducer is a critical and important component of any ultrasonic measurement system. Transducers convert electrical energy into acoustic energy and vice versa to transmit and receive sound waves. The ... -
Fabrication and Characterization of a Low-Frequency Array for a Hybrid PZT-CMUT Transducer
Siu, Hoi Yi (Master thesis, 2021)Piezocomposite materials consist of a periodic structure of active piezoelectric materials and passive polymer materials. Piezocomposite material is widely used in medical ultrasound transducers due to the advantages of ... -
Feasibility of acoustically engineered backing material for ultrasound transducer : additive manufacturing of tungsten loaded thermoplastic polyurethane (TPU)
Billah, Md Mehedi (Master thesis, 2023)The present study aims to examine the acoustic characteristics of a metamaterial made from tungsten loaded thermoplastic polyurethane (TPU) using COMSOL simulations. The investigation encompasses the simulation of single ...
