Micro Magnetic Field Sensor Based On Terfenol-D/PZT/Terfenol-D Magnetoelectric Composites

Abstract:

Article Preview

A new type of magnetic sensor based on magnetoelectric(ME) composites has been designed and fabricated. The ME composites has a Terfenol-D/PZT/Terfenol-D structure and its ME coefficient is 0.36 V/cm Oe at room temperture. The sensor has AC magnetic measurement ranges from 0.02 Oe to 12 Oe, reaches a sensitivity of 5×10-3 Oe and has a flat response within 15 kHz. The sensor is equipped with a pre-amplifier and an Root Mean Square(RMS) value convertor.
