A Compact Wearable System for Detection and Estimation of Open Wound Status In Diabetic Patient

In this paper, a new smart health embedded system that can notify users the status of an open wound to assure correct cicatrisation in real-time for ulcer foot in diabetes prevention has been designed. Specifically, this system monitors the healing process through the saturation of exudate in the absorbent dressing and the pathogen of infection by estimating the top gas of wound based on the various bacteria’s metabolites. The collected information has been transmitted on portable devices in real time to inform the patient the current condition of wound and give advice. Finally, the algorithm of diabetes wound healing process is explored in this work, which can also be applied for related medical research in the diabetes preventions. The measurement results have an error of 0.9% and 2.3%, respectively for temperature and humidity in detection of cicatrisation. In the evaluation of pathogen of wound infection, the error of predicting the concentration of different gases (Sulfo-compound, Ethanol and Aldehyde) was only 2.8%.
