Piezoelectric ceramic with tubular, spherical and curved surface

The piezoelectric ceramic is to use a special processing to make different shape, which could get large displacement by adjusting the cylinder length to thickness ratio,   and obtain offset axis by dividing outside electrode. The piezoelectric ceramic is used as ultrasonic receiving and transmitting sensor in thin tubes or other fields.
