Water sensors are a type of level sensor that can be used in various applications requiring the sensing of water levels, such as in dams, nuclear power plants, water pipes, water tanks, and dehumidifiers. In particular, water sensors in water ingress monitoring systems (WIMS) protect lives and property from disasters caused by water leakage and flooding. Here, a resistive water sensor for WIMS that incorporates poly(3,4-ethylenedioxythinophene):poly(styrene sulfonate) (PEDOT:PSS) grafted with poly(ethylene glycol) methyl ether (PEGME) (PEDOT:PSS-g-PEGME copolymer) as high-conductivity electrodes and laser-treated PEDOT:PSS-g-PEGME copolymer as the low-conductivity resistive component is reported. The configuration of the water sensor is modeled as two parallel resistors (Rlaser treated PEDOT:PSS||Rwater) when water comes into contact with the sensor surface. The two-resistor configuration exhibits a better performance in comparison with single-resistor configurations comprising only PEDOT:PSS-g-PEGME copolymer or laser-treated PEDOT:PSS-g-PEMGE copolymer. Moreover, PEDOT:PSS-g-PEGME copolymer is applied to the sensor to improve the stability of PEDOT:PSS in water. We demonstrate that the sensor can detect the water level in real time with high sensitivity and accuracy, and thus has potential in applications for monitoring water-related hazards.

基于PEDOT：PSS-g-PEGME共聚物和激光处理的阻水传感器，用于进水监控系统。

水传感器是一种水位传感器，可用于需要水位传感的各种应用中，例如在大坝，核电站，水管，水箱和除湿机中。特别是，进水监控系统（WIMS）中的水传感器可保护生命和财产免受因漏水和洪水造成的灾难的影响。在这里，WIMS电阻式水传感器结合了聚（乙二醇）甲醚（PEGME）（PEDOT：PSS-g-PEGME共聚物）接枝的聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS） ）作为高电导率电极，并报道了经激光处理的PEDOT：PSS-g-PEGME共聚物作为低电导率电阻元件。水传感器的配置建模为两个并联电阻器（经过Rlaser处理的PEDOT：（PSS || Rwater）当水与传感器表面接触时。与仅包含PEDOT：PSS-g-PEGME共聚物或激光处理的PEDOT：PSS-g-PEMGE共聚物的单电阻器配置相比，双电阻器配置具有更好的性能。此外，将PEDOT：PSS-g-PEGME共聚物应用于传感器，以提高PEDOT：PSS在水中的稳定性。我们证明该传感器可以高灵敏度和高精度实时检测水位，因此在监测与水有关的危害方面具有潜在的应用价值。将PSS-g-PEGME共聚物应用于传感器，以提高PEDOT：PSS在水中的稳定性。我们证明该传感器可以高灵敏度和高精度实时检测水位，因此在监测与水有关的危害方面具有潜在的应用价值。将PSS-g-PEGME共聚物应用于传感器，以提高PEDOT：PSS在水中的稳定性。我们证明该传感器可以高灵敏度和高精度实时检测水位，因此在监测与水有关的危害方面具有潜在的应用价值。
