Abstract
A current sensor, responsive to the first power of a current to be measured, utilizes a piezoelectric element located between a current-carrying conductor and a permanent magnet having its north-south poles aligned normal to the direction of current flow through the conductor. The substantially constant magnetic field provides a sensor output, taken from electrodes upon opposite surfaces of the piezoelectric member, which is proportional to the first power of current flowing in the single conductor.
