Hello everyone,
I'm synthesizing a conductive hydrogel made of a PVA, CMC BORAX, and active carbon. I'm trying to measure its conductivity by impedance: What I'm doing is putting the hydrogel on a coin cell and measuring its impedance. Is it the right method? Because I'm assuming that the hydrogel is the electrolyte and both sides of the coin cells are the electrodes? is it possible even if the hydrogel is conductive?
Thank you for your help.
Myriam.
Dear Myriam Ghodhbane ;
The electro-conductivity of the conductive hydrogel can be measured using the ECG acquisition data indicating method, as detailed in the following reference.
