3Ease of manufacture
If linear conducting wires coated with charged dielectric material are used for electrodes and electrets, then processing cost is reduced, but manufacturing precision may be affected
Solution Approach 1:
The patent changes the fundamental parameters of the manufacturing approach by transitioning from precise lithographic patterning to a coating-based method. By controlling the coating thickness, wire geometry, and charge distribution parameters, the invention achieves sufficient functional precision for electrostatic induction without requiring the ultra-precise dimensional control of semiconductor fabrication, thus reducing costs while maintaining adequate performance.
Solution Approach 2:
The patent applies local quality by ensuring that the charged dielectric coating on the linear conducting wires has the necessary properties only where needed for electrostatic induction. The coating is applied to the surface of the wires in a controlled manner, providing the required electrical characteristics at the electrode-electret interface while allowing simpler, more cost-effective manufacturing methods to be used for the overall structure.
