Chronic skin wounds resulting from burns, diabetes, ulcers, and other medical conditions can overwhelm the skin's regenerative capabilities, leading to persistent infections and even amputations in severe cases. Over 10 million patients with chronic wounds are treated yearly in the United States, with an estimated cost of more than US $40 billion in annual spending for treatment. Even with the latest advancements in IoT-based connected health, smart bandages can only aid in drug release to prevent infections. However, a smart bandage that can non-intrusively diagnose or monitor the burn wound's state does not exist. To address this shortcoming, in this work, we present a non-intrusive, affordable, real-time wound assessment device, that employs mmWave patch sensor for burn wound prognosis through electrical impedance spectroscopy.
