Abstract

In this paper, a device is developed for detecting external dc magnetic field, which is constructed from a piezoelectric unimorph and an energized coil. The working principle of the device is based on the coupling of the Ampere force in the energized coil exposure to external magnetic field and the piezoelectric effect of the piezoelectric unimorph. Experiments have been conducted to verify the feasibility of the device. The device shows a high output voltage of 0.5984V at the dc magnetic field of 0.1 mT. The large dc magnetic field response of the proposed structure driven by the Ampere force makes this device hopeful in application of dc magnetic field sensors.
