METHOD FOR APPLYING BIAS OF MAGNETIC FIELD SENSOR AND STRAIN SENSOR, AND THE MAGNETIC FIELD SENSOR AND STRAIN SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a method for applying bias for a magnetic field sensor and for a strain sensor, whereby the bias can be applied using a simple arrangement, in place of a magnetic field bias by a winding wire, and to provide a magnetic field sensor and a strain sensor.;SOLUTION: There are provided the magnetic field sensor 1, a PZT piezoelectric element 3, attached to a rear face of the magnetic field sensor 1 for generating primary strain, and a power supply 4 for impressing a voltage on the PZT piezoelectric element 3.;COPYRIGHT: (C)2002,JPO
