Abstract
This work utilizes PEDOT:PSS/PANI composite polymer to develop a low-power and low-cost CO 2 sensing material. With proper material composition, the developed CO 2 sensing material overcomes a major problem, selectivity to humidity, of traditional conductive polymer sensors. Based on experimental results, it shows a CO 2 detection range from 1000 ppm to 20000 ppm. It also has an independent response to relative humidity ranging from 55% to 90%. In addition, the developed sensing material has experimentally demonstrated its power consumption of 10 μW. Based on these experimental results, the developed CO 2 polymer sensor demonstrates a good potential for chemical/environmental applications of Internet-of-Thing technologies.
