Abstract
A sensor device for monitoring bioelectric data from a human body includes a flexible dielectric substrate, a plurality of sensors (electrodes) distributed on the substrate for sensing the bioelectric data, and an electrically conductive network distributed on the substrate connecting the sensors to a terminal portion of the substrate. Integrated flexible joints permit a certain amount of elasticity in and allow relative movement between at least two of the sensors when the sensor device is placed onto the human body.
