Abstract

A gyroscope based on Coriolis effect and fabricated by Carbon Nanotube (CNT) was presented. The gyroscope was designed 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 μm was used for emitter and an anode with a bias angle is etched by Focused Ion Beam (FIB) which is set to the opposite to the CNT. An electrode is set near the CNT tip, which is employed to pulling the CNT for mechanical resonances by an AC voltage. The CNT with a resonate frequency of 1 MHz and mechanical quality factor Q of ~400 was tested at rotation speed of 20 rad.s.
