The structure circuit of the sulfonic acid lithium humidity sensitive components

The structure circuit of the sulfonic acid lithium humidity sensitive components is as shown in the figure. The production process: you can dip the sulfonic acid lithium on the insulating substrate to form the humidity sensing substrate, then you can make the interdigital-type carbon electrode at both sides of the humidity sensing substrate, the carbon electrode is led out by the gold-plated wiring unit. Because the humidity sensing substrate can adsorb or release the water molecules to change the resistance value, so we can the relative humidity value by detecting the resistance value between the electrodes.
