Abstract
What is specified is a piezoelectric transformer () having a surface structure which has at least one protruding surface structure segment (), wherein the piezoelectric transformer has a contour () and is suitable for discharging a gas in conjunction with a counter electrode () for generating a plasma, wherein the surface structure is configured such that the gas discharge takes place at a multiplicity of discharge initiation points () on the contour (). A width of the surface structure segment () is smaller than the width of the piezoelectric transformer ().
