From Swell to Signal: Hydrogel Polymer Design in Biosensor Performance

Overview

This project explores the development of safer, more effective materials for wearable health sensors, such as those used in heart monitoring. I engineered soft, hydrogel-based materials using natural polymers derived from plant and shell sources, and systematically tested different compositions to evaluate their water retention, moisture stability, and electrical conductivity. These properties are critical for maintaining consistent performance and comfort in skin-contact devices. Current sensor materials are often synthetic, which can lead to skin irritation and reduced functionality over time due to dehydration. This project aims to identify an optimal bio-based formulation that enhances performance while prioritizing biocompatibility. The findings have potential applications in improving the design and reliability of future wearable medical technologies.
