Wei Wang,Wei Wang,Siu Wing Or,Qingwen Yue,Yaoyao Zhang,Jie Jiao,Bo Ren,Di Lin,Chung Ming Leung,Xiangyong Zhao,Haosu Luo +10 more
TL;DR: In this article, a cylindrically shaped ultrasonic linear array has been designed, fabricated, and characterized based on the improved flexibility of as-prepared PIMNT/epoxy 1-3 composite, which achieved an ultrabroad bandwidth (−6 dB) of 128%, which is a significant improvement over the plane linear array.
Journal ArticleDOI
Ternary piezoelectric single-crystal PIMNT based 2-2 composite for ultrasonic transducer applications
Wei Wang,Wei Wang,Siu Wing Or,Qingwen Yue,Yaoyao Zhang,Jie Jiao,Chung Ming Leung,Xiangyong Zhao,Haosu Luo +8 more
TL;DR: In this article, a PIMNT/epoxy 2-2 composite ultrasonic transducer was designed, fabricated, and its performance was compared with those of a single-crystal ultrasonic Transformer.
Journal ArticleDOI
High frequency transducer for vessel imaging based on lead-free Mn-doped (K0.44Na0.56)NbO3 single crystal
Jinpeng Ma,Saidong Xue,Xiangyong Zhao,Feifei Wang,Yanxue Tang,Zhihua Duan,Tao Wang,Wangzhou Shi,Qingwen Yue,Huifang Zhou,Haosu Luo,Bijun Fang +11 more
TL;DR: In this article, a lead-free single-crystal transducer was used for vessel imaging with a center frequency of 51.8 MHz with a −6 dB bandwidth of 70.2%.
Journal ArticleDOI
Phase transition behavior and defect chemistry of [001]-oriented 0.15Pb(In1/2Nb1/2)O3-0.57Pb(Mg1/3Nb2/3)O3-0.28PbTiO3-Mn single crystals
Xing Liu,Bijun Fang,Ji Deng,Hao Deng,Hong Yan,Qingwen Yue,Jianwei Chen,Xiaobing Li,Jianning Ding,Xiangyong Zhao,Haosu Luo +10 more
TL;DR: In this article, a modified Bridgman method was used to grow PIMNT-Mn single crystals with a rhombohedral perovskite structure, which exhibited complex dielectric behavior after polarization, and the temperature and electric field induced ferroelectric phase transitions were investigated by the temperature dependent unipolar strain curves.
Journal ArticleDOI
Broadband and high sensitive time-of-flight diffraction ultrasonic transducers based on PMNT/epoxy 1-3 piezoelectric composite.
Dongxu Liu,Qingwen Yue,Ji Deng,Di Lin,Xiaobing Li,Wenning Di,Xian Wang,Xiangyong Zhao,Haosu Luo +8 more
TL;DR: These TOFD ultrasonic transducers based on PMNT/epoxy 1–3 composite exhibit considerably improved performance over the commercial PZT/ep oxygen 1-3 composite TOFD Ultrasonic transducer.
