Hydrogel coating flexible pH sensor system for fish spoilage

A hydrogel coating flexible pH sensor system is described for real-time wireless monitoring of fish spoilage. On absorption of the acidic or basic volatiles the hydrogel pH changes, which in turn changes the voltage across the pH-sensitive electrode pair shifting the response potential of the sensor. The sensitivity of the flexible pH A hydrogel coating flexible pH sensor system was formed by connecting a flexible pH sensor with FBES for the detection of TVB-N in fish meat packaging ( Fig. 1 (e) ). Fig.2 (a) illustrates the schematic of the laser direct scribing process. The laser direct scribing system consists of PC, fiber laser, and galvo.Hydrogel coating flexible pH sensor system for fish spoilage
