Experimental Measurement of Diffusion Coefficient of Polyimide Film for Capacitive Humidity Sensors
Polyimide (PI) film is widely used as the key component of the capacitive humidity sensor, whose diffusion coefficient has a significant impact on the sensor’s dynamic characteristics, but is rarely discussed. This paper provides a test method and processes for effective diffusion coefficients of wa...
