Abstract: Systems and methods for monitoring power in a conductor. A flex circuit may include multiple layers including a voltage sensing layer, a coil layer, and a ground layer. The coil layer includes traces that form a coil structure around a conductor when the flex circuit is wrapped around the conductor. The coil layer generates a voltage that may be integrated to determine a current in the conductor. When the flex circuit is wrapped around the conductor, the voltage sensing layer is closest to the conductor. The voltage sensing layer forms a capacitor with the conductor. Using an adjustable capacitive voltage divider, the voltage of the conductor may be determined from a voltage signal received from the voltage sensing layer.
