A new type 3 × 3 aligned array needle-bar electrode structure in vertical position are designed to realize ionic wind with a certain gas flow velocity.In condition that the distance between needle-bar is 3 mm

the distance between rows is 8 mm

the ballast resistance is 12 MΩ

the discharge resistance is 12 MΩ

the test resistance is1 kΩ

in ambient air

at room temperature

without air flow

the stable corona discharge between needle-bar electrode is realized

and it is verified by discharge waveform recorded by oscilloscope

luminous image recorded by digital camera and discharge volt-ampere characteristics curve.At the same time

the discharge current and the flow velocity of ionic wind increase with the row number of array increasing.The structure is easy to be fabricated by MEMS technology

which can be used in portable analyzer.
