The working principle of Focused Shockwave Therapy System is to arrange hundreds of piezoelectric crystals on a concave surface. When an external electric field passes through the crystals, their volume changes, generating pressure waves; as the crystals return to their original state, they produce tension waves. All the piezoelectric crystals vibrate together, emitting shockwaves that are collected by an ellipsoidal reflector, focusing the entire energy precisely on the treatment area.
