P1D-4 Characteristics of a Novel Magnetic Field Sensor Using Piezoelectric Vibrations

Abstract

This report presents novel configurations for magnetic field sensor using piezoelectric vibrations, which are based on the simple electromagnetic physics and require no semiconductor materials. First, we present the principle and basic characteristics of the proposed sensor with a piezoelectric bending vibrator. Second, the sensor is applied to a scanning probe of a permeability microscope for surface mapping.
