研究目的
To develop a resistive water sensor for water ingress monitoring systems (WIMS) that can detect water levels in real time with high sensitivity and accuracy, using PEDOT:PSS-g-PEGME copolymer and laser treatment.
研究成果
The resistive water sensor based on laser-treated PEDOT:PSS-g-PEGME copolymer demonstrates high sensitivity and accuracy in detecting water levels in real time. The sensor's design, incorporating both high-conductivity and low-conductivity regions, shows improved performance over single-resistor configurations. This sensor has potential applications in monitoring water-related hazards, such as in WIMS for ships and other environments prone to water leakage.
研究不足
The study focuses on the development and initial testing of the sensor in controlled conditions. Further research is needed to evaluate the sensor's performance in real-world applications, including long-term stability and resistance to environmental factors.
