Portable iot system for non-invasive nutrient monitoring
A robust, affordable, and user-friendly IoT-based portable device that non-invasively tests micronutrient levels in sweat, saliva, and urine using AI-interpreted colorimetric sensors. Ideal for real-time, on-site analysis of vitamins and minerals.
Overview
The Portable IoT System for Non-Invasive Nutrient Monitoring offers a groundbreaking solution for real-time, on-site detection of essential micronutrients in bodily fluids such as sweat, oral fluid, and urine. This innovation leverages a combination of IoT-based portable multisensor devices and AI-driven analytics to deliver robust, affordable, and simple testing solutions. Users can easily perform tests using colorimetric paper strips with immobilized reagents, which are then analyzed by a smartphone app using artificial neural networks to provide selective quantification of micronutrients.
