The conductivity of graphite powder is an important factor in the finished product of graphite powder, and there are many factors affecting the conductivity of conductive graphite powder. For example, the ratio of graphite powder, external pressure, environmental humidity, humidity and even light. Graphite powders are available.

        1. Some other factors for measuring resistivity of conductive graphite powder. Conductivity will change with the change of external factors, and it is sensitive to contrast. Previous microphones were made of graphite powder, that is, the electrical conductivity of graphite powder was changed by the noise, and the current was changed and then the analog signal was generated. As you can imagine, you need to test his conductivity of the experimental environment request.
