A piezoelectric generator using a master cylinder for a vehicle is provided to charge a battery with electric energy by using a stacking-type piezoelectric element and to recover the energy by a pressure wasted when the vehicle stops. A piezoelectric generator for a vehicle includes a master cylinder(10), a stacking-type piezoelectric element(20), a charging device, and a battery. The master cylinder is installed in the vehicle and generates an oil pressure for brake force of the vehicle. The stacking-type piezoelectric element is installed at one side of the master cylinder and outputs an AC(Alternating Current) high voltage according to an applied external force. The charging device is electrically connected to the stacking-type piezoelectric element. The battery is connected to the charging device and is charged by the charging device. |
