| Abstract: | Starting with the sensitivity to vibration of STM, the exploration and research on theory,techniques and realized methods of nano vibration sensor based on tunneling effect are performed. A sample model with piezoelectric ceramic has been developed,and some experiments are made in the vibration detecting. The experimental results show that vibration sensor based on tunneling effect has high sensitivity,good frequency characteristic and vibratory response characteristic consistent with STM. |
