We demonstrate the working of a solvent treated paper resistor for resistor, capacitor filter circuit operation and relative humidity sensing. The paper resistor has been fabricated by solvent treatment method, where a piece of photocopier paper is treated with sodium chloride solvent and upon deposition of sodium chloride micro crystals at the mic...

The charging-discharging form of signal voltage variation across the paper capacitor indicates that the paper capacitor behaves exactly in the same way as an ordinary ceramic or electrolytic capacitor. For high and low input square voltage signal, the voltage variation across the capacitor is shown in Fig. 2(a) and 2(b) respectively. Fig. 2(c) shows the photo- graph of the paper RC filter circuit.
