Wearable monitoring networks are designed to augment and improve daily life. These systems require sensors and various electrical components to be mounted on the body. We propose a novel technique of using a DC powerline-carrier communication system to integrate the system components. This simplifies the wiring and the routing of connectors, and reduces the system weight and bulk. We use conductive fabrics as the transmission medium of the system. A method of predicting the DC behavior of such a garment is presented, and its utility in the design of such garments is discussed.
