Chloride Selective Gold Coated Fiber Bragg Grating Sensor

Our research aims at a chloride-sensitive gold-plated Fiber Bragg Grating (FBG) sensor that can detect chloride with good resolution. This sensor is designed for applications in water treatment plants and swimming pools where safety and quality matter. And for better results, we use Atomic Layer Deposition (ALD), which carefully places a gold layer on the FBG to ensure it is sensitive, selective and stable. Manufacturing has a lot of vital phases. First the FBG is scratched to expose the surface and then a layer of gold is applied by ALD. It is a process that allows us to control the characteristics of the sensor and assure it is optimized for the detection of chloride with accuracy. This is then extensively tested to ensure the reliability and efficiency of the sensor under extreme conditions. This ALD-coated gold surface is the key to the performance of the sensor that allows it to measure accurately. What makes this research so valuable is what it can be used for. It is important to monitor chloride for public health and safety purposes — particularly in drinking water and dialysis fluid. It could also be applied to water quality monitoring and industrial process optimization. It is research not only that introduces a new sensor but also solves some practical problems in chloride detection. This construction improves water quality and protection at many sites by providing a reliable and accurate measurement instrument. It sets a framework for future advances in environmental and industrial sensor technology.
