Abstract: PURPOSE: A piezoelectric material for a multilayer actuator in a haptic device and a fabrication method thereof are provided to minimize power consumption by performing a sintering process at a low temperature. CONSTITUTION: Copper oxide of 0.1 to 10 mole% is added to a compound. The compound is indicated as a chemical formula 1. A haptic device is laminated by using a piezoelectric material. A mixture is manufactured by a wet mixing process (S110). A first powder is formed by drying the mixture (S120). [Reference numerals] (S110) Step where a below-mentioned compound is produced by wet-mixing raw powder including PbO,ZrO_2,TiO_2,NiO,ZnO, and Nb_2O_5 according to a mol rate; (S120) Step where the compound is dried and calcined at around 700-1,000 °C in order to create a first powder; (S130) Step where copper oxide of 0.1 to 10 mole % is added to the first powder and the powder is wet-mixed and dried to produce a second powder; (S140) Step where the second powder is pressed and sintered at around 700-1,000 °C in order to create a piezoelectric body
