Jagged discharge electrodes powered by triboelectric generator

This Letter proposes jagged discharge electrode with low discharge voltage, which is fabricated by the MEMS fabrication technique. The voltage multiplier, as energy accumulation module, was analysed and modified. Finite-element analysis has been done for simulating the arc generation. The discharge form of this device was investigated through the damage on the two electrodes by microscopic images. An encapsulated liquid-based triboelectric generator was utilised to charge high voltage for self-powering the system. This novel discharge system is promising for applications in sterilisation, ozone production and arc lightening.
