Function Pain relief Rehabilitation Sport injury treatment Anti-Aging lose weight Working Principle RET/CET RF Capacitive Electric Transfer(CET) is a method that allows the RF electrical current to be transferred"by capacity"(principle of the electrical capacitor) to the patient's body via a moveable external application electrode.This is covered with aninsulating film which acts as dielectric and the body acts as a second plate of the capacitor. A retumn plate closes the circuit.The electric circulation through the resistive medium formed by the live tissues increases its temperature. RET (Resistive Electric Transfer) Targeted Radiofrequency Diathemy Therapy Device works deeper targeted tissue than current superficial diathermy therapy devices.it transfers high frequency electromagnetic energy through the tissues of the body creating selective tissue hyperthermy,it can decompose body fatty cell,so as to loss weight.
