Direct-Printed Micro-Supercapacitor Biosensor for Painless Glucose Monitoring

Diabetes is a major global health challenge, with Qatar experiencing some of the highest prevalence rates in the region. Traditional glucose monitoring methods, such as finger-prick tests, are painful, inconvenient, and limited to discrete readings that may miss critical fluctuations. This project proposes a novel wearable biosensing system for continuous, non-invasive glucose monitoring. By delivering real-time data, it empowers patients to make timely decisions and enables early detection of hypo- and hyperglycemia. Integrated with smartphones via Bluetooth, the system supports personalized care and remote monitoring, addressing growing demands on Qatar’s healthcare system. The sensor features high sensitivity and resolution, fabricated using inkjet printing of advanced 2D nanomaterials like graphene or MXenes. Locally manufactured using regional materials, it promotes affordability, scalability, and national biomedical self-sufficiency. Micro-supercapacitors embedded in the sensor enhance performance, while solid-state electrolytes ensure safe skin contact. The system aligns with Qatar’s digital health vision, offering improved patient experience, enhanced clinical decision-making, and valuable public health insights through aggregated data. This user-centered platform represents a significant step toward innovative, accessible diabetes management.
