This project aims to create a T-shirt with basic technology, designed to help sportspeople. Moreover, it aims to detect the fundamental vital parameters, using sophisticated sensors, possibly being viewed by an external person via a technological device connected via Bluetooth. Features: • Heartbeat detection (bpm) • Blood saturation detection (SpO2) • Position detection via GPS • Skin hydration detection If any of these vital parameters suffer more or less serious alterations, an alarm will activate. Potential technical components: • Heart rate sensors • Sensors for blood saturation • Sensors for skin hydration • Ultra mini battery • Ultra mini GPS • Arduino board • Waterproof fabric suitable for all kinds of sports
