- piezoMEMoirS: Enhanced Visualization of Biopsy Needle
- Enhanced Visualization of Biopsy Needle using a MEMS Actuator Precise localization of needle tip is important for the biopsy. A mini actuator that radiates a low-intensity ultrasound burst was manufactured with MEMS technology. Interference between the radiated and diagnostic pulses was observe ...
- piezoMEMoirS: Electromagnetic Bandgap Etructure
- Electromagnetic Bandgap Structure Containing High-k Dielectric Ceramics Electromagnetic bandgap structure (EBG) is an artificial dielectric composite, in which dielectric materials with high and low permittivities are periodically arranged in space. EBG can be rega ...
- piezoMEMoirS: Wireless Accelerometer
- A Wireless Accelerometer Using Micromachined Piezoelectric Sensor Vibration monitoring is often carried out for machines fault diagnosis. The state of art vibration sensors are manually and repetitively installed, which causes inconsistency in the measurement results. The long cables, lar ...
- piezoMEMoirS: Acoustic Transducer
- Acoustic Transducer Dimension of the in-plane poled piezoelectric diaphragm: electrode width=60 μ m; electrode spacing=250 μ m; radius=3.5 mm. The effective coupling coefficient is 3.08 %. The quality factor Q value is 39.96. Schematic diagram o ...
- piezoMEMoirS：In-plane Poled Piezoelectric Diaphragm
- In-plane Poled Piezoelectric Diaphragm Double-sided spiral electrodes can generate an in-plane poling scheme. The diaphragm utilizes d 33 effect to generate the in-plane strain (thus a d 33 mode transducer ), which is converted to an out-of-plane displacement due to the constrai ...

- 新荷叶 忆植物园 误入华林 去年相似曾经 如故鹅湖 锦鳞吞吐浮萍 警禽却步 问可是 昨岁鹡鸰 又闻槐下 鸣蝉领唱群蛉 抛却轮滑 儿童捉放蜻蜓 整顿婚纱 新人顾盼徐行 铜亭扫罢 叹春芳 老却园丁 & ...
- 工匠造诗——雪夜停林
