A second solution is to choose proper component materials which can reduce the required voltage for discharging, and which will then be compatible with integrated circuits [3,4].
As a result of cheap materials and environmental friendly technologies, the method is a good choice.

Inlet material was air, air densityρ=1.225 Kg/m3, viscosity coefficient μ=1.76×10-5 Kg/m·s.
The smaller angles would increase the length of inlet section and enlarge the volume of equipment, which would lead to more materials wasting.
