Humidity sensor

With the increase of humidity, the macromolecule swelling, the internal free volume increases, the carrier increases, and the activation energy of the polymer polyelectrolyte counterions can be reduced

Low, the migration rate increases, the impedance of the material decreases. Conversely, when the humidity of the environment changes, the water molecules will be released from the ionic polymer, which will increase the resistance of the material

Big. By determining the impedance changes, the relative humidity in the environment can be monitored.
