Claim 10:
11. A method for detecting rotation, comprising the steps of:
providing a rotation sensor comprising: (i) a substrate having a top surface and an interior bottom surface; and (ii) an electrode module positioned on the top surface of the substrate and comprising a first set of electrodes and a second set of electrodes;
generating, by the first set of electrodes, a bulk acoustic wave directly into the substrate, wherein at least a portion of the bulk acoustic wave is transduced into a shear wave upon reflection on the interior bottom surface of the substrate without use of a reflector;
detecting, by the second set of electrodes, the shear wave; and
determining, based on the detected shear wave, an effect of Coriolis force on the sensor.
