Wireless Textile Moisture and pH Sensor for Wound Care
Written by Corrisa Heyes
True textile organic electronic sensors embedded in the fibers that make up a fabric using PEDOT:PSS to transform biofluid analysis into electronic signal for chemical/hormone detection in sweat has shown to be quite reliable. Working with organic electrochemical transistors (OECTs) allows for the development of a selective two-terminal sensor that brings lab-on-fabric capabilities to medical gauze and provides a medium for real time, wireless remote (RFID readout) monitoring of a wound with tunable impedance sensitivity that results in a truly passive device. This allows for real time measurements without need to redress a wound and will last the life of the bandage.
