A Study on The Development of Humidity Sensor Using Polyimide Film

  • 발행 : 1994.07.21

초록

In this work, polyimide thin films fabricated by the electrophoretic deposition are investigated as a humidity sensing material. Capacitance and impedance are measured with increasing relative humidity to find the nature of the film. From the results, the polyimide humidity sensor is not classified impedance change type but capacitance change type and appear more sensitive in the region of higher humidity than that of lower humidity.
