  • Angular velocity sensor
    Patent number: 7997135
    Abstract: An angular velocity sensor includes a drive electrode section (26) for inputting a drive signal for driving a detecting element (21), a monitor electrode section (28) detecting the drive status of the detecting element (21) and outputting a monitor signal, and a sensing electrode section (27) outputting a sensing signal, which is generated due to an angular velocity given to the detecting element (21). The drive electrode section (26), the monitor electrode section (28), and the sensing electrode section (27) each have a lower electrode formed on a substrate, a piezoelectric film formed of a piezoelectric material on the lower electrode, and an upper electrode formed on the piezoelectric film.
