Beschreibung
Zusammenfassung:	A rotation sensor, including: (i) a substrate having a top surface and an interior bottom surface; (ii) an electrode module positioned on the top surface of the substrate and including a first set of electrodes configured to generate 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, and a second set of electrodes configured to detect the shear wave; and (iii) a controller in communication with the first set and second set of electrodes and configured to determine, based on the detected shear wave, an effect of Coriolis force on the sensor.
