This project presents BreezySure, an innovative breath monitoring biosensor designed to enhance asthma management through user-centred design. Recognising that existing medical devices often appear clinical and discourage consistent use, BreezySure focuses on comfort, aesthetics, and intuitive interaction to promote daily engagement. The device combines ergonomic design, ease of maintenance, and a visually appealing form to foster curiosity and awareness about respiratory health. By providing real-time feedback and encouraging regular use, BreezySure aims to improve adherence to asthma management practices, empower users to take control of their well-being, and transform medical monitoring into a more accessible and motivating experience.
