摘要	The development of electrochemistry-based sensors is central to in-situ atmospheric corrosion monitoring of materials under conditions of both outdoor and indoor exposures. In this work, an improved design with an exposed Cu teeth height in the two member electrodes of the traditional EIS-based atmospheric corrosion sensor makes the sensor more sensitive under the thin electrolyte layer. With the noble design, the improved sensor exhibits a high sensitivity in surface electrolyte generation when the NaCl deposition is higher than 20 mg/m2, and a good corrosion rate response to NaCl deposition as low as 2 mg/m2. The grooves between adjacent exposed Cu teeth facilitate the formation of electrolyte layer under the hygroscopic effect of NaCl deposition, and thus improve sensitivity of the sensor to low NaCl deposition. Therefore, the improved sensor has broad potential applications in field conditions to monitor low NaCl deposition induced thin electrolyte layer evolution and corrosivity assessment of the atmosphere.
