فناوری آرایه مبدل اولتراسونیک میکروماشین شده پیزو-کامپوزیت با فرکانس بالا برای تصویربرداری بیومدیکال

In this monograph, piezoelectric materials used for high frequency transducers is introduced first. Next, the benefits and theory of piezo composites is presented, followed by the design criteria and fabrication methods. Biomedical applications using piezo composites micromachined ultrasound transducers (PC-MUT) and arrays will also be reported, in comparison with other ultrasound transducer techniques. The final part of this monograph describes challenges and future perspectives of this technique for biomedical applications Explores the current advancement in high frequency piezoelectric crystal micromachined ultrasound transducers and arrays and their biomedical applications. Piezoelectric ultrasound transducers operating at high frequencies (> 20 MHz) are of increasing demand for medical imaging and biological particle manipulation involved therapy.
