This paper deals with preliminary decontamination performances obtained from a plasma jet generated by a piezoelectric transformer. This low voltage supply solution (<10V) is investigated as a compact and safe solution for the decontamination of medical thermo-sensitive devices. Promising reduction rates are obtained on Pseudomonas aeruginosa and Staphylococcus aureus bacteria with an argon plasma jet at atmospheric pressure about 2.5W input power.
