A Cost -Effective Photonics-based Device for Early Prediction, Monitoring and Management of Diabetic Foot Ulcers (G.A. 871908) 

[H2020 Call: ICT-05-2019: Application driven Photonics components
a) Innovation Actions]

Within PHOOTONICS project, the aim was the development of innovative, reliable and cost-effective (in terms of almost zero operational cost and high return of investment) photonic-driven devices for Diabetic Foot Ulcers (DFU) monitoring and management which can be applied for wide use. The proposed devices combine passive infrared photodetectors with active illuminators. Specifically, it will be delivered

  • a passive HSI photo-detector, sensitive at NIR spectrum of 700nm-1000nm with an active tuneable diode illuminator, operating at NIR spectrum, for optimising reliability (in terms of sensitivity, specificity and accuracy) in detecting peripheral oxygen and tissue saturation- SpO2/StO2 and oxyhaemoglobin/deoxyhaemoglobin, at a spatial resolution of approximately 50pixels/cm, 
  • a passive Mid-IR photodetector, sensitive at spectrum 5.7μm-9.3μm with a Quantum Cascade Laser (QCL) optimized to capture additional tissue attributes such as elastin, collagen, lipid, amino amino-acids and carbohydrates necessary information for DFU early prediction and management at a resolution scale approximately of 10pixels/cm. and 
  • thermal-IR sensing component capable of detecting hyperthermia/hypothermia distributions in ROIs with different levels of resolution for the PRO and In-Home version (full HD and 10 pixels/cm respectively).
