Abstract

An apparatus for generating an atmospheric pressure plasma is disclosed. In an embodiment an apparatus includes a first support element and a piezoelectric transformer supported by the first support element, wherein the piezoelectric transformer is supported at a position at which an oscillation node is formed when the piezoelectric transformer is operated at an operating frequency that is lower than its parallel resonant frequency, and wherein the piezoelectric transformer is configured to generate a non-thermal atmospheric pressure plasma.
