ENERGY HARVESTING COLD ATMOSPHERIC PLASMA GENERATOR
The invention relates to a plasma applicator (1) for applying a non thermal plasma, particularly for disinfection purposes. The plasma applicator (1) comprises an electrically driven plasma sourse (2) generating the non- thermal plasma and a electrical power source (3) provinding electrical energy, wherein the power source (3) is connected to the plasma source (2) and powers the plasma source (2).Further, the plasma source comprises a first electrode and a second electrode, wherein the first and second electrodes are spaced apart by at least one dielectric layer, and wherein the first and/or the second electrode is/are arranged directly on the surface of the dielectric layer or embedded in the dielectric layer, Further, the power source (3) comprises an energy harvesting device (4), wherein the energy harvesting device (4) converts ambient energy into the electrical energy needed for the operation of the plasma source (2). For example, a piezoelectric generator can be used for powering the plasma source (2).
