YAWO is a low-cost connected insole designed to monitor plantar pressure in real-time for patients with T2D. Equipped with multiple pressure sensors and integrated electronics, the insole provides dynamic feedback to both users and doctors, alerting them to anomalies and helping users correct their walking posture before complications arise. Built using open-source hardware and low-cost sensors Real-time alerts via pressure feedback Designed for preventive care to reduce diabetic foot-related amputations 

Prototype Evolution First Prototype: Leather insole with off-the-shelf pressure sensors Limitations: Bulky wiring and low load capacity (1–2kg) Second Prototype: 3x6 meshed copper braids for 18 sensor points Used Velostat + copper intersections Improved flexibility, ergonomics, and integration Final Prototype: Merged sensor design and PCB into one streamlined unit Highly ergonomic and reliable design suitable for clinical use Additional Information Focus on open-source accessibility to benefit global diabetic populations Emphasis on affordability and manufacturability Tested and presented during the SDG School STEAM sessions
