    摘要: Provided is a gyroscope using a surface acoustic wave (SAW) and an angular velocity measurement method. The gyroscope includes an SAW resonator generating a first SAW, generating Coriolis force using an interaction between a velocity component of the first SAW and applied angular velocity on a metallic dot layer disposed in a certain position, and generating a second SAW using the Coriolis force, an SAW sensing oscillator generating a third SAW and receiving a fourth SAW, which is the third SAW reflected and returning after causing interference due to the second SAW, and a measurement device measuring a level of the applied angular velocity using variations in time of receiving the fourth SAW.
