PIEZOELECTRIC SENSOR AND METHOD FOR MANUFACTURING THEREOF

摘要

PURPOSE: A piezoelectric and a manufacturing method thereof are provided to improve piezoelectric properties by forming electrodes on both sides of piezoelectric materials mixed with tourmaline powder and permanent magnet powder. CONSTITUTION: Piezoelectric materials(10) are made by mixing ferroelectric inorganic materials with tourmaline powder. Electrodes(20) are formed on both sides of the piezoelectric materials. PZT is used as the ferroelectric inorganic materials. The electrode is made of conductive materials.
