A QUT (Queensland University of Technology) Centre for Materials Science research team has developed a prototype electronic device built from fish waste, paving the path for safe, flexible, and sustainable wearable health sensors. The study aims to create wearable biocompatible biosensors that might provide real-time health monitoring without endangering environmental sustainability, comfort, or safety. That makes them ideal for future wearable health monitors.”Since chitosan is non-toxic and biodegradable, it is already widely employed in biomedical applications. According to Professor Sonar, biocompatible transistors might be the foundation for wearable biosensors that monitor vital signs and detect disease biomarkers.
