An ultrasound applicator designed to turn off an ultrasound system when an application area has reached too high of a temperature may include an ultrasound head； and a temperature sensor operatively attached to the ultrasound head and to the ultrasound delivery system. When the temperature sensor senses a temperature above a predetermined value, the ultrasound system may shuts off. The ultrasound applicator may additionally include an electronic module, wherein the temperature sensor is operatively connected to the electronic module which is operatively connected to the ultrasound deliver unit, and the electronic module includes a temperature controlled switch designed to turn off power to the ultrasound delivery unit when the temperature sensor senses the temperature above the predetermined value.
