In this presentation, we propose a cost-efficient smart bandaid for quick and reliable assessment of chronic wounds. The assessment is done using the transmit-reflect principle of wound-data modulation from an interrogator. The RF modulation of the data is done via the use of a textile-based voltage-controlled oscillator. The latter captures the electric [DC] signal provided by the electrochemical sensor dipped in the wound fluid containing various uric acid concentrations. The wound assessment was done based on a threshold found to be 0.4 mM with respect to which the severity or restoration of the damaged tissue [wound] is evaluated. The average sensitivity of the proposed system was found to be 44.67 MHz/mM and the maximum power consumption 380 microWatts. The system uses low-cost materials that are easy to manufacture and can be used by any patient or medical professional.
