The ultrasound waves are generated by a piezoelectric effect caused by the vibration of a quartz ceramic disk within the head of the probe. The ultrasound waves that pass through the skin cause a vibration of the local soft tissues. This vibration or cavitation can cause a localised deep heating effect but no sensation of heat will be felt.
