“…6 Due to that, conducting polymers (CP) such as polyaniline (PANI), polypyrrole (PPy), poly (3,4-ethylenedioxythiophene) (PEDOT), and polythiophene (PTh) are usually implemented as sensor materials due to their chemical and physical properties that can be signicantly changed in response to external stimuli such as temperature, pH, stress, moisture, electric elds, magnetic elds, light and chemical compounds. [7][8][9][10] CP based thin lms can exhibit some advantages over metal-based thin lms in terms of their exibility, easy-processing, low-cost and manageable-waste. They can be fabricated through spin coating, drop casting, dipping, chemical graing or chemical vapour deposition method.…”
