Airity has developed a cold plasma device that selectively kills microorganisms without damage to human cells or tissue through generation of high levels of reactive species from the air using short high-voltage pulses. The major benefit of this technology over current methods is its potential efficacy against the most robust organisms, including drug-resistant bacterial strains, fungi, and biofilms. A key innovation is the device’s compact, high efficiency, pulsed power source. By leveraging new high frequency circuit innovations developed at Stanford, as well as recent improvements in power semiconductors, Airity’s power supply is considerably more efficient and less energy intensive than currently available options for producing cold air plasmas. Having already demonstrated very high DC-to-DC conversion efficiencies, Airity is now validating the performance and capabilities of their device. Broad adoption of this technology could drastically reduce the use of toxic chemicals and energy demanding sterilization methods.
