  • Microplasma jet devices, arrays, medical devices and methods
    Patent number: 8957572
    Abstract: Preferred embodiments of the present invention include microplasma jet devices and arrays in various materials, and low temperature microplasma jet devices and arrays. These include preferred embodiment single microplasma jet devices and arrays of devices formed in monolithic polymer blocks with elongated microcavities. The arrays can be densely packed, for example having 100 jets in an area of a few square centimeters. Additional embodiments include metal/metal oxide microplasma jet devices that have micronozzles defined in the metal oxide itself. Methods of fabrication of microplasma jet devices are also provided by the invention, and the methods have been demonstrated as being capable of producing tailored micronozzle contours that are unitary with the material insulating electrodes.
