- Several major piezoelectric ceramic materialsBarium titanate piezoelectric ceramics (3BaTiO. Barium titanate is the first piezoelectric ceramic made and widely used, and its electromechanical coupling coefficient is very high. Compared with other piezoelectric ceramics, it has a lower curie point and its electromechanical.The performance is veBasics of Piezoelectric Ceramics November 19, 2018
- The new type focused ultrasound transducersThe use of HIFU piezo ceramic to treat local tumors, how to enhance the treatment effect and minimize the radiation damage to healthy areas is an important issue. In response to this problem, many researchers have designed and developed some new transducers. Some researchers have proposed to use mulHIFU Piezo information October 25, 2018
- Evaluation of HIFU transducer performanceThe performance indicators describing the transducer are operating frequency, electroacoustic efficiency, and transmitted sound power. The performance of the HIFU ceramic transducers is described below, and the performance of the four in vitro focused transducers is described separately. (1) OperatiBasics of Piezoelectric Ceramics October 25, 2018
- What’s the electronic phased array focusing HIFU transducerThis type of transducer is a type of transducer that has been discussed in recent years. Its design is based on the Huygens principle. The transducer is arranged in an array in a space by a plurality of mutually independent piezoelectric wafers. Each wafer is called an array element. When each arrayHIFU Piezo information October 23, 2018
- What’s the high intensity focused ultrasound transducerHigh intensity focused ultrasound HIFU is an emerging in vitro non-invasive treatment of tumor technology. The physical principle of treatment is: through a certain form of ultrasound focusing transducer, the ultrasound energy is focused on the target tissue, and the target tissue is rapidly heatedBasics of Piezoelectric Ceramics October 22, 2018
- piezoelectric ceramic plate used for guitar pickupExperimental principleThis experiment utilizes the positive piezoelectric effect of piezoelectric ceramics. Using the piezoelectric ceramics installed in the guitar resonance box, the seven sounds from the center C to B (including B) in the C major scale are plucked by the player, and the electric sBasics of Piezoelectric Ceramics October 22, 2018
- The application of using a piezoelectric ceramic to identify the tones of instrumentsThis study utilized the principle of piezoelectric effect of piezoelectric ceramics and consisted of two parts of experiments. The first part is to use the positive piezoelectric effect of piezoelectric ceramics, install piezoelectric ceramic sheets in the resonance box of the guitar, and pluck theBasics of Piezoelectric Ceramics October 19, 2018
- Advantages and Disadvantages of HIFU ceramics transducerCompared with surgery, HIFU ceramic transducer for machine is non-invasive and has few complications. Compared with radiotherapy, H IFU can obtain a therapeutic dose in one irradiation, and can also repeat the treatment of residual lesions or locally recurring lesions. The use of H IFU does not exclHIFU Piezo information October 23, 2018
- What ‘s the tumor treatment of HIFU piezo ceramicDifferent parameters of piezoelectric ceramics can be selected according to the needs of the therapeutic dose at the time of treatment to achieve the best effect. Highly vascularized tumors although clinical exposure times often take more than 3s, early studies have shown that short-term exposure isHIFU Piezo information October 18, 2018
- Immune function of HIFU treatmentAbout immune function, who observed the tumor regressed at the same time, the distant metastasis also subsided that HIFU treatment can improve the body's specific and non-specific immunity to tumors. The killing effect of tumor cells can indirectly promote the development and maturation of helper lyHIFU Piezo information October 18, 2018
