Abstract

Abstract: The piezoelectric direct discharge sustained using a high‐performance piezoelectric transformer (PT) with a voltage transformation ratio of >1, 000 was used for the generation of an atmospheric pressure plasma jet (APPJ). The ionization gases used are ambient air and compressed dry air. The APPJ was characterized using capacitive probe measurement, ozone concentration measurement, and activation area determination. The activation experiments were conducted on a high‐density polyethylene. The activation area was visualized using pure formamide test ink (58 mN/m) and captured by a digital camera. The influence of gas flow, PT power, and the distance between the PT and the substrate were investigated. Abstract : This study deals with the properties of worldwide first atmospheric pressure plasma jet powered by piezoelectric transformer and operated in ambient air. The operation principle and characteristics of this novel device are presented. The correlations between the surface activation efficiency, ozone production rate, and the microdischarge number per oscillation cycle are shown. New methods for electric characterization and plasma activation area evaluation are proposed.
