摘要
PURPOSE: An integrated sensor with piezoelectric material and an apparatus comprising the same are provided to improve the sensibility of voltage, current, and magnetic sensors through simple configuration by amplifying magnetic field change through a piezoelectric element and sensing it.;CONSTITUTION: In an integrated sensor with piezoelectric material and an apparatus comprising the same, a sensor(610) senses vibration, voltage, current, and magnetic field and generates a signal. An amplifier(620) amplifies the signal from the sensor. A filter unit(630) performs filtering of a signal and remove a nose. A controller determines the polarity of the magnetic field based on the polarity of the signal from the sensor unit.;COPYRIGHT KIPO 2012
