摘要：
Disclosed herein is a growth plate stimulation-type portable growth promotion apparatus including two-phase ultrasonic vibration generators and Light Emitting Diode (LED) devices. The ring-shaped two-phase ultrasonic vibration generators have a center hole. Each of the LED devices is provided in the center hole of the each two-phase ultrasonic vibration generator. The two-phase ultrasonic vibration generators includes a ring-shaped vibration stator configured to have a center hole a first electrode layer provided under the vibration stator a second electrode layer provided under the first electrode layer and a piezoelectric ceramic group layer configured to include a first piezoelectric ceramic group for generating an A phase and a second piezoelectric ceramic group for generating a B phase. Growth plates are stimulated using two-phase ultrasound projected from the two-phase ultrasonic vibration generators and light projected from the LED devices.
