Assignee: TDK ELECTRONICS AG
Field: Chemical engineering (Chemistry)
Classification: CPC H | IPC H

Claim 0:
1. A device comprising:
a piezoelectric transformer;
a driver circuit configured to apply an input signal to the piezoelectric transformer;
evaluation electronics connected to the driver circuit; and
a field probe comprising a metallization forming a measurement point, at which the field probe is configured to determine a local field strength of an electric field produced by the piezoelectric transformer,
wherein the field probe is configured to measure the field strength of the electric field at the measurement point,
wherein the driver circuit is configured to:
adapt the input signal while taking into account measurement results of the field probe, and
transmit the input signal applied to the piezoelectric transformer to the evaluation electronics,

wherein the evaluation electronics are configured to:
further process measurement values recorded by the field probe,
determine an output signal determined by the piezoelectric transformer from the measurement values recorded by the field probe, and
compare the input signal with the output signal, and

wherein the device is configured to produce a non-thermal atmospheric pressure plasma.
