Advances in science and technology have led to the development of open surgery to a smaller trauma. Various interventional is minimally invasive treatment methods, including percutaneous radio frequency ablation and microwavHIFU Piezo information October 17, 2018
- Measurement of high intensity focused ultrasound sound fieldFiber grating refers to a segment of fiber with grating function formed by changing the distribution of refractive index in the fiber by ultraviolet radiation. It only reflects a certain wavelength of wave, which is equivalent to a kind of mirror. When there is strain or temperature change, it willHIFU Piezo information October 17, 2018
- What’s the Hydrophone detectionA hydrophone is a transducer that converts an underwater sound pressure signal into an electrical signal. When the pressure (acoustic disturbance) on the piezoelectric material piezo ceramic tubes changes, the charge distribution inside the piezoelectric material changes proportionally and is reflecBasics of Piezoelectric Ceramics October 16, 2018
- Sound field detection of high intensity focused ultrasound HIFU piezoHigh intensity focused ultrasound (HIFU) has developed rapidly in recent years and has become a research hotspot in the medical ultrasound engineering field. HIFU surgery is to concentrate the low-intensity ultrasound in vitro into the body through a certain focusing method (acoustic lens, concave sHIFU Piezo information October 16, 2018
- Study of ultra-micro PZT piezoelectric ceramic powderThe polarized PZT piezo ceramic becomes an ordered arrangement due to the polarization electric field forcing the disordered 90°domain and 180°domain steering in the unit cell, and the spontaneous polarization axis in the unit cell is longer than the non-spontaneous polarization axis.
