The invention relates inter alia to a device (10) for producing an atmospheric pressure plasma (20, 20a, 20b, 20c, 20d), especially for treating a substrate, said device comprising a unit (11, 11a, 11b, 11c) produced from a piezoelectric material. Said unit has at least one primary region (12, 12a, 12b, 12c) in which at least two electrodes (17a, 17b, 17c) for applying a low AC voltage are arranged, and a secondary region (13), along the longitudinal direction (L) of which potential differences are produced when the primary region is incited. The invention is inter alia characterized in that the secondary region (13) comprises two partial regions (14, 14a, 14b, 14c, 15, 15a, 15b, 15c) that have an opposite polarity along the longitudinal direction (L). |
