Development of piezoelectric micromachined ultrasonic transducers
Piezoelectric micromachined ultrasonic transducers (pMUTs) are an example of the application of MEMS technology to ultrasound generation and detection, which is expected to offer many advantages over conventional transducers. In this work, we investigate pMUTs through novel design and fabrication methods. A finite element (FE) model, with original tools to measure device performance, was develo...
متن کاملAbsolute Ultrasonic Measurements with Piezoelectric Transducers
The absolute calibration of a piezoelectric transducer refers to the determination of the relationship between the electrical and acoustical quantities for a transducer coupled to a solid. It is shown how a well-characterized ultrasonic system, consisting of source,structure and receiver can be used to make such measurements for transducers operating as sources or receivers. Results are given, ...
متن کاملA Novel Rotary Piezoelectric Motor Using First Bending Hybrid Transducers
We report a novel rotary piezoelectric motor using bending transducers in this work. Three transducers are used to drive a disk-shaped rotor together by the elliptical movements of their driving tips; these motions are produced by the hybrid of two first bending vibration modes. The proposed piezoelectric transducer has a simple structure as it only contains an aluminum alloy beam and four piec...
متن کاملEquivalent Electrical Simulation of High -Power Ultrasonic Piezoelectric Transducers by Using Finite Element Analysis
Finite element method (FEM) has been employed extensively for vibration modal analysis of piezoelectric transducers and devices. In recent years, there has been a growing interest in the simulation and analysis of piezoelectric transducers by using equivalent electrical circuit models. This paper has been devoted to such approach for two designed and fabricated ultrasonic sandwich transducers h...
متن کاملMulti-Objective Design Optimization of a Linear Brushless Permanent Magnet Motor Using Particle Swarm Optimization (PSO)
In this paper a brushless permanent magnet motor is designed considering minimum thrust ripple and maximum thrust density (the ratio of the thrust to permanent magnet volumes). Particle Swarm Optimization (PSO) is used as optimization method. Finite element analysis (FEA) is carried out base on the optimized and conventional geometric dimensions of the motor. The results of the FEA deal to ...
