FBAR resonators can be manufactured on ceramic (Al 2 O 3 or alumina), sapphire, glass or silicon substrates. However silicon wafer is the most common substrate due to its scalability towards mass manufacturing and compatibility with various manufacturing steps, often typical to semiconductor manufacturing, needed.
Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb).
