This is the supplementary data for the dissertation titled "Reader-friendly Edible Binarycodes and Sensors Based on Smart Hydrogel". This dissertation addresses the critical challenges of counterfeiting and product deterioration in the global food and medicine industries. It introduces four innovative prototypes to tackle these issues. The first prototype establishes a system for creating magnetic microparticles embedded with superparamagnetic colloids, forming binary code matrices for product authentication. The second prototype employs a Physical Unclonable Functions (PUF) algorithm to enhance the safety of On-Dose-Authentication (ODA) binary codes, making them readable even in basic laboratory conditions. The third prototype introduces a humidity indicator that reacts to high humidity by bending and rolling, providing a safe means to detect moisture exposure in food packages. The fourth prototype utilizes an alginate TTI bead encapsulating a natural colorant, betacyanin, to monitor and indicate temperature abuse in perishable products through irreversible thermochromic changes. These innovations hold promise for enhancing product quality control, tracking, and anti-counterfeiting measures in the food and medicine industries. The movies in this dataset are supplementary information regarding the magnetic microparticles embedded with superparamagnetic colloids and the humidity indicator separately.
