... adopt a symmetric weighting electrode to match the symmetric distribution of the even parts of the strain in order to introduce a no-phase delay low-pass filter to tailor the sensor transfer function. Both the design concept and the experimental results are detailed herein. In comparison, adopting...

...Yuan Shu-Qing,; Xu Qing-Yu,; Zhang Ling Experiments are performed to actively suppress vibration of a flexible four-bar linkage mechanism bonded with piezoelectric materials as sensor and actuator. The control system is built up with computer, A/D and D/A converter, low-pass filter, voltage...
