Discharge element

This is a discharge element that formed along the mica surface, on which discharge electrodes are formed on both sides of a mica sheet.

Having the mica sheet as the dielectric, high-voltage electrode is located on one side and low-voltage electrode on the opposite side.
One of its main characteristics is that it generates large volumes of ion.
Also, since the dielectric is thin and flexible, it can be attached to circular and cylindrical objects.


  1. (1) Generates ion in large volumes.
  2. (2) Since the element is flexible, it can be attached to circular and cylindrical objects.
  3. (3) Uniform electrical discharge across the entire length of an element, which prevents uneven discharge.
  4. (4) The element is thin which can contribute to saving space.


  1. (1) Static eliminator
  2. (2) Ion generator
  3. (3) Electrostatic charger
