A rotating motion sensor includes at least one electroacoustic resonator to stimulate a surface acoustic wave. The at least one electroacoustic resonator is configured so that rotation of the at least one electroacoustic resonator about an axis of rotation causes a change in resonance frequency of the at least one electroacoustic resonator. The at least one electroacoustic resonator includes oscillating structures configured to oscillate in a first direction that is a direction of propagation of the surface acoustic wave and/or a second direction that is transverse to the direction of propagation of the surface acoustic wave.
