piezokeramische vielschichtstruktur with regular polygon cross-section

摘要

A piezoelectric ceramic body in the form of a prism, which has a plurality of insulating layers arranged over one another and made of a piezoceramic material, the insulating layers being at least regionally separated from one another by a conducting layer made of an electrode material. The top view of the insulating layers at least approximates the shape of an n-gon, especially a regular n-gon, n being greater than four and especially being six, eight, or ten. Furthermore, the conducting layers cover each of the insulating layers so extensively that two adjacent insulating layers are only in direct contact with one another in the region of narrow dead zones regionally located at the outer edge of the insulating layers.
