Atmospheric cold plasma
Plasma is created by exciting a gas through the introduction of energy, for example using high voltage.
Various technical principles can be used to generate atmospheric cold plasma. The ActivCellpen uses dielectric materials, i.e. materials that are weakly or not at all conductive, which allow discharge pulses to be transferred to a conductive surface such as human skin.
The resulting cold plasma comprises numerous physical and chemical components. The combination of these components is ultimately responsible for the medicinal effect.
Due to the low electrical currents, the technology is well tolerated by patients when used as intended.
