This study utilized Bartovation’s humidity detection test paper to provide a real-time visual indication of the moisture content in their dressing device. This study introduces a water-powered, electronics-free dressing as a novel and cost-effective solution for treating chronic wounds. The device performed comparably to expensive biologics and electronic-based treatments, showing promise as a practical and effective alternative for chronic wound care. Our humidity indicator changes its color from blue to light pink when water is added to the inlet pad. The indicator returns to its blue color when the separator dries due to water evaporation.
