6 FAQs about [Piezoelectric ceramics can be used as capacitors]

Can piezoelectric ceramic be used for capacitive compensation of PT?

Therefore, the inductive behaviour of the piezoelectric ceramic can be considered for the capacitive compensation of PT. A PZT-4 sample (Hunan Jiayeda Co., Ltd., China) with dimensions of 30 × 20 × 0.4 mm 3 is chosen for conducting the detailed inductive behaviour analysis.

Do class I capacitors have a piezoelectric effect?

Class I capacitors are not ferroelectric and therefore do not exhibit a piezoelectric effect. It is also important to understand that not all ferroelectric capacitors will experience a piezoelectric effect. A specific combination of component construction and circuit usage conditions must exist in order to cause the capacitor to vibrate or ring.

What is the role of capacitive impedance in piezoelectric ceramics?

In energy harvester applications, multilayered (Pb,Zr)TiO 3 piezoelectric ceramics have a role of voltage source with capacitive impedance. Due to considerable impedance in voltage sources, the role of impedance matching between the source and output terminal is more critical.

What happens if piezoelectric ceramic and PT are the same?

If the PT and the piezoelectric ceramic are manufactured with the same dimensions, the resonant frequency of PT will be slightly higher than that of the ceramic and fall between the two characteristic frequencies of the ceramic. This effect is attributed to the division of the PT surface electrode.

Can a piezoelectric “Bulk” ceramic be produced?

The possibility of producing piezoelectric “bulk” ceramics lies in the possibility of breaking the symmetry properties of the ceramic, via the application of a high strength electric field (poling process). This is possible due to the ferroelectric nature of the crystallite grains, of which ceramic is composed.
