Influence of surface micro-beams with large deflection on the resonance frequency of a quartz crystal resonator in thickness-shear mode vibrations被引量：1
《Theoretical & Applied Mechanics Letters》2017年第2期72-75,共4页Chi Luo Jiemin Xie Yuantai Hu 
supported by the National Natural Science Foundation of China(11272127 and 51435006);the Research Fund for the Doctoral Program of Higher Education of China(20130142110022)
We study the dynamic behavior of a quartz crystal resonator （QCR） in thickness-shear vibrations with the upper surface covered by an array of micro-beams （MBs） under large deflection. Through taking into account t...

Spiral piezoelectric transducer in torsional motion as low-frequency power harvester被引量：1
《Applied Mathematics and Mechanics(English Edition)》2013年第5期589-596,共8页王海仁 胡洪平 杨嘉实 胡元太 
supported by the National Natural Science Foundation of China(Nos.10932004 and 11272127)
A structure consisting of a spiral piezoelectric transducer and a concentrated mass is proposed as a low-frequency piezoelectric power harvester. A theoretical model is developed for the system from the theory of piez...
