Abstract

An apparatus for producing a plasma including a control circuit which is electrically connected to a piezoelectric transformer in order to excite the piezoelectric transformer. A hand-held device that uses the apparatus. The piezoelectric transformer is constructed of several layers. The control circuit is implemented on a circuit board, and the piezoelectric transformer is held over the circuit board by means of a region of a first end. A high voltage is applied to a second free end of the piezoelectric transformer. The plasma is produced at atmospheric pressure.
