Piezoceramic multi-layer structure with regular polygon cross-sectional area

A piezoelectric ceramic body, comprising:

• a plurality of insulating layers arranged one over another and made of a piezoceramic material;
• and
• a plurality of conducting layers made of an electrode material and by which the plurality of insulating layers are at least regionally separated from one another, wherein:
• a plan view of at least the plurality of insulating layers at least approximates a shape of an n-gon,
• n is greater than four,
• the plurality of conducting layers cover each insulating layer such that two adjacent ones of the plurality of insulating layers only come in direct contact with one another in a region of narrow dead zones,
• the region of narrow dead zones is regionally located at an outer edge of the plurality of insulating-layers,
• the plurality of conducting layers extend to the outer edge of the plurality of insulating layers at alternating faces of the n-gon, and
• the plurality of conducting layers do not extend to the outer edge of the plurality of insulating layers at adjacent faces of the n-gon.
