提出了一种基于科里奥利效应的碳纳米管(CNT)陀螺仪。碳纳米管是在x方向上的振动，当绕z方向旋转时，y方向就会产生加速度。多壁碳纳米管的固有频率取决于其内径、外径和长度。碳纳米管是由静电力驱动到其固有频率的。发射极采用长度为1m的碳纳米管，利用与碳纳米管相反的聚焦离子束刻蚀具有偏置角度的阳极。在碳纳米管尖端附近设置电极，利用交流电压拉动碳纳米管进行机械共振。
A gyroscope based on Coriolis effect and fabricated by Carbon Nanotube (CNT) will be presented. A CNT is vibration at x direction, when there a rotation around z direction, acceleration happens to the y direction. The natural frequency of MWCNT is depending on the inner diameter, outer diameter and length. The CNT was driven by the electrostatic force to its nature frequency. A CNT with a length of 1 ?m was used for emitter and an anode with a bias angle was etched by Focused Ion Beam (FIB) which was set to the opposite to the CNT. An electrode was set near the CNT tip, which was employed to pulling the CNT for mechanical resonances by an AC voltage.
