Classification: CPC H | IPC H

Claim 42:
43. A device comprising:
a piezoelectric transformer;
a driver circuit configured to apply an input signal to the piezoelectric transformer; 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 produced at the measurement point, and
measure at least one of the following: a pressure, a temperature, a humidity, a conductivity, an ozone concentration, a gas composition, an ion concentration or a particle concentration,

wherein the driver circuit is configured to:
adapt the input signal while taking into account measurement results of the field probe, and
take into account at least one of the following during adaptation of the input signal:, the pressure, the temperature, the humidity, the conductivity, the ozone concentration, the gas composition, the ion concentration or the particle concentration, and
wherein the device is configured to produce a nonthermal atmospheric pressure plasma.
